Résumé:

Actuellement, dans beaucoup de pays, ce sont quelques défis pour la construction de tunnels dans des régions montagneuses, la prédiction du degré d'affectation à un niveau local et régional des systèmes hydriques, les effets secondaires comme, la subsidence du terrain, l'altération de la qualité de l'eau, la diminution du niveau phréatique, le drainage des systèmes hydrodynamiques qui ont été stockés durant de longues périodes géologiques, etc. Par l'antérieur, en Colombie, il existe la construction de deux tunnels de 8.7 Km chacun avec 100 m2 et 18 m2 de section, dans le projet du « Tunnel de la Ligne », qui est placé dans la cordillère centrale des Andes, avec une géologie hautement fracturé et très conducteur dans les zones de faille, lesquelles présentent des taxes de 4 -25 L/s d'infiltration de l'eau souterraine, avec becs de drainage de 150-200 L/s à la sortie du tunnel de plus court de section et avec la réduction des flux des courants superficiels, présents dans les cinq bassins que la zone du projet croise. Maintenant, pour estimer le comportement régional des eaux souterraines, étant données le manque d'information hydrogéologique. Il a été proposé de réaliser une caractérisation hydrogéologique plus conforme à la réalité, à partir d'une campagne d'essais hydrauliques (Packer Tests) à l'intérieur de la section plus grande du tunnel, cela à la fin d'estimer, les paramètres de conductivité hydraulique et le coefficient de stockage dans les zones d'intérêt avec l’affluence ou présence d'eau pendant la phase de construction et qui avec le modèle conceptuel, les simulations numériques et les observations de champ, a pu se déterminer le comportement hydrogéologique de l'eau souterraine au niveau local et régional dans le massif fracturé et les oeuvres souterraines effectués dans ce moment avec la conception et la construction de ce projet.

MODELACIÓN ANALÍTICA Y NUMÉRICA PARA LA CALIBRACIÓN DE PARÁMETROS HIDRÁULICOS O PREDICCIÓN DE CAUDALES DE INFILTRACIÓN EN OBRAS

SUBTERRÁNEAS - TÚNELES

Autor: Luis Camilo Suescún Casallas1

Desde el punto de vista cuantitativo, uno de los problemas de diseño y seguridad que son claves antes de realizar la excavación de un túnel en profundidad con formaciones geológicas saturadas, es la evaluación de las tasas de descarga de aguas subterráneas que se pueden presentar durante el proceso de perforación o construcción de un túnel [Perrochet y Dematteis, 2007], la magnitud del máximo caudal que fluirá en su sección, el periodo de tiempo en el que se mantendrá ese máximo caudal, su variación a lo largo del tiempo, los descensos generados durante los avances de excavación y el tiempo necesario para que se estabilice el caudal [Samper y Lorenzo, 2008].

A través de modelos analíticos o simulaciones numéricas (e.i., Anagnostou [1995], Molinero et al. [2002], Zaidel et al. [2010], Hokr et al. [2014], Baietto et al. [2015]) se puede conocer el comportamiento y afectación que tendrá el medio con la excavación. Si se dispone de buena información, los modelos numéricos pueden ser representativos de lo contrario darán aproximaciones inadecuadas con errores numéricos importantes. Por otra parte, las formulaciones analíticas proporcionan una solución aproximada, a partir de configuraciones de flujos idealizados y simplificaciones que condicionan el problema, al ser fáciles de usar y de requerir pocos parámetros en su cálculo. En general, estas formulaciones suelen ser útiles para realizar cálculos preliminares, verificar soluciones numéricas y en algunos casos para descartar hipótesis [Samper y Lorenzo, 2008].

Con este trabajo, se desea comparar y conocer la utilidad de la modelación analítica con un software desarrollado por el autor (TunWaterFlow V 1.0) que basa su funcionamiento en la formulación propuesta por Perrochet y Dematteis [2007] y modelación numérica con el uso del software comercial Feflow V6.2® (p11) para calibrar (parámetros) y predecir los caudales de infiltración en túneles profundos. A partir de tres casos de estudio (Túnel exploratorio de Modane - Francia e Italia, Túnel de La Línea - Colombia y Túneles Grupo 1 Puerto Berrío - Alto Dolores – Remedios - Colombia), se establecen los requerimientos y configuraciones para el modelo analítico y numérico en 2D y 3D. Respecto al modelo numérico se encuentran relaciones directas con la configuración de la malla (tipo triángulo y cuadrilátero), el avance de la excavación y el desarrollo de una metodología (con un código en Matlab r2013a®) para cuantificar el flujo de entrada en los nodos que definen el contorno del túnel, los cuales incluyen series temporales y condiciones especiales tipo Dirichlet que tienen en cuenta la presión atmosférica. La limitación de la presente versión, al no tener combinación de mallas (mallas no estructuradas) y el cambio de orden de magnitud de las propiedades hidráulicas (conductividad hidráulica – K, coeficiente de almacenamiento específico – Ss) de los materiales que generan errores numéricos y oscilaciones en el flujo del modelo.

ABSTRACT [ 326 Words ]

One of the most important problems in the construction of tunnels in porous and fractured media, is the groundwater infiltration. The

lack of knowledge and due quantification can generate instability of the rock mass, increases pressure on temporary support systems

and permanent changes in the geo-mechanical properties of materials, ground movements (subsidence), reduction of surface and

groundwater resources, environmental impacts, increase time and cost of the project, among others.

Some authors have studied this subject with analytical models to quantify the infiltration flows in a tunnel, from formulations at steady

state with constant hydraulic head, instant drilling, etc. However, the behavior of the excavation is progressive and the tunnel drilling

heterogeneous formations and the application of these formulations at steady state are not recommended.

Perrochet [2005a] established a formulation in transient state that considers the progressive drilling in homogeneous and

heterogeneous media [Perrochet and Dematteis, 2007]. This last approximation considers a simplification of geology in vertical layers

with different hydraulic parameters (K and Ss) and with a convolution integral, it is possible to calculate the discharge into the tunnel

(direct problem). However, there is not a tool to do a calibration of flow observed in a portal automatically (inverse modeling).

To solve this limitation, in this work, it was adopted the formulation proposed by Perrochet and Dematteis [2007] and solve the inverse

problem with a software developed in Matlab R2013a and called “TunWaterFlow V 1.0”. This software makes a coupling of the

existing mathematical model and two calibration algorithms: evolutionary algorithm + simplex algorithm (SCE-UA) and MonteCarlo

simulations (GLUE) to allow automatic adjustment of the flow simulated with the observed flow, is possible with comparison the

objectives functions. For purposes of showing the utility of this software, it has tested with calibration exercises in three tunnels that

were presented during excavation, peak flows infiltration of 200 L/s each one (La Línea Tunnel – Colombia, Modane Tunnel–

France/Italy and Pajares Tunnel – Spain).

Since a quantitative point of view for the hydrogeologist, one of the most important design and security issues that present with the

excavation of deep tunnel in heterogeneous and saturated geological formations, is give a good estimation of the rate of discharge of

groundwater with the construction, estimate the magnitude of peak flow that will flow through in the tunnel contour, the time period will

remain infiltration and variation of the flow rate over time and his stabilization (steady state).

These predictions can be possible using analytical and numerical models with enough data recollected in field, but almost always is

not possible for their high costs and the estimations will have erroneous approximations given the input data.

In the actually, the analytical formulations may be provided the hydrogeologist modeler a tool to approximate quickly the seepage flow

in the drilling with several simplifications of problem and few parameters used in the calculus. Then with this results, the modeler can

improve the numerical model and in some cases to rule hypothesis for the conceptual model.

An example of the above, is evidenced in this work using analytical and numerical models to estimate the seepage flow and

calibration the hydraulic parameters with an observed flow in several case studies in Colombia (La Linea Tunnel) and France/Italy

(Modane Tunnel). To achieve this synergy, it was necessary to use a software developed by the author (TunWaterFlow) which bases

its calculation on the proposed analytical formulation for deep tunnels of low diffusivity by Perrochet and Dematteis [2007] and

commercial software (FEFLOW V6.2®) that provide the best tools to the modeler for make two-dimensional and three-dimensional

models an easy and quick way.

Some interesting results in seepage flow were found for the numerical models with the mesh, time step and BC's...

Special hydraulic tests to understand the impact on groundwater with the

construction of La Linea Tunnel and the changes of hydrogeological conditions

in the fractured massif of Colombian Los Andes

ABSTRACT n° 2195

Donado Leonardo David [email protected] Colombia


Sub Topic :

Keywords : TUNNEL, HYDRAULIC TEST, HYDROGEOLOGY

Comments :




Currently for the hydrogeologist, the construction of underground works (tunnels) demand a level of knowledge and expertise to the

great geological and hydrogeological uncertainty in the mountainous terrain. A not understanding or adequate characterization

generate conceptual and numerical models without consistency with the local or regional environment and a real estimation of the

impact on surface and groundwater resources during the construction.

An example is found in Colombia, with the La Línea Tunnel project. This project involves drilling two tunnels of 8.7 km each one,

sections of 18-100 m2 and depth of 800 m and during the construction generated a reduction of surface currents and maximum

groundwater infiltration 200 L/s, associated with highly fractured materials, highly conductive fault zones ~25 L/s and lack of

knowledge the geological and hydrogeological in the fractured massif of Colombian Los Andes.

Against this background, it was proposed to do a forensic hydrogeological study to quantify the hydraulic parameters (hydraulic

conductivity and storage coefficient) of some geological formations that crosses this project very influential for the country. With the

infiltration points identified during the excavation, we proceeded in two phases inside the tunnel larger section: to make a drilling

campaign of 30 boreholes of 480 m - PHI and a campaign of hydraulic tests (Packer, Slug Test, Pulse, pumping at a constant flow) -

PHII.

Once PHASE I finished, stability problems were presented in wells for the high fracturing of the rock. Given this, it was only possible

to do 21 hydraulic tests that were interpreted for EPHEBO free code [UPC,2002] that use the analytical solution of general model and

it was established a hydraulic characterization for 5 of 6 sectors of the tunnel, with 5 orders of magnitude for K, 10-10~10-6 m/s and a

value for S~10-3. Later, these results helped improve local conceptual model and be analytical and numerical input for the prediction

of flow and effect on surface and groundwater resources models.
