Import Formats

The Datgel CPT Tool natively supports a range of common CPT data file formats. Where applicable the CPT Tool also imports dissipation test data.

Users can customise the gINT import correspondence files to control which field and table data imports to.

Choose to import 1 file, multiple files or a folder of files.

Supported import file formats include:

• Access

• AGS 3.1, AGS 3.1 RTA 1.1 and AGS4

• A.P. van den Berg Gorilla!

• Datem Neptune (CDF)

• Douglas Partners

• GEF 1.1.0 and 1.0.0

• Geomil PlotCPT

• Gregg Drilling (COR)

• gINT Excel

• gINT CSV

• Hogentogler (CPD)

• Pagani (CPT and DAT)

• ProbeDrill

• Simple Delimited Depth qc fs u

• Swedish Geotechnical Data Format (SGF)

• Vertek

Upon request we will develop import functions for commonly used file formats.

Soil Behaviour Type

The CPT Tool is supplied with six soil behaviour type (SBT) interpretation methods:

• Eslami Fellenius (1997)

• Ramsey (2002)

• Robertson (1990)

• Robertson, Campanella, Gillespie and Greig (1986)

• Schmertmann (1978)

• Schneider, Randolph, Mayne and Ramsey (2008)

Additional methods may be defined by users.

The SBT can be summarised onto your existing borehole description lithology/stratigraphy table.

Your existing material graphic code can be associated with each SBT number, geotechnically insignificant layers may be excluded, and thin layers of the same type (fine/coarse) can be appended together.

Comparison Log Report

CPT Logs

A range of sophisticated log reports are included. All reports include options to:

• Control plot scales in numerous ways; Either set minimum and maximum values, or have the Tool automatically find the maximum value in a PointID or Project and round up to the nearest number e.g. 5 or 10

• Easily define line and data marker types, colours and thickness from INPUT

• Control number of major divisions on log plots

• Display of design lines

• Display lines across the log identifying sea water level, seabed level, natural/original level below a reclamation

• Control number of metres per page

• Display qc or qt moving average, stepped average, and strata average

Dynamic Log Reports for Analysis

• A4, A3, Letter and 11x17 paper sizes

• At output time, select up to 10 columns to display on the logs, and optionally define the column widths

Comparison Logs for Ground Improvement

• Display two CPT PointIDs on one log report with data related by elevation

• Applicable to ground improvement and reclamation projects

Fixed Log Reports for Mass Production

Correlations

User Definable Correlation Formulas

The Datgel Formula Tool is the first way for a user to write a formula in gINT Input without writing complex VBA code. Simply define the referenced fields, and write your correlation formula in a standard formula syntax.

• Reference any related field in the database

• Built in mathematical and statistical functions

• Define result format, i.e. decimal places or significant figures

• Results may be numbers or text

• Store your common formulas in the library, and project specific formulas in the project

• Data averages

• Data extrapolations

Liquefaction Potential

Cyclic resistance ratio evaluated using:

• Jefferies & Been (2006)

• Robertson & Wride (1998) / NCEER

Pile Axial Capacity

Evaluated to:

• Bustamante and Gianselli / LCPC (1982)

Preconfigured correlations

• Coefficient of lateral earth pressure, K0

• Coefficient of volume, mv

• Compression Index, Cc

• Constrained Modulus, M

• Effective angle of friction, φ’

• Effective cohesion, c’

• Hydraulic conductivity (permeability), K

• Overconsolidation ratio, OCR

• Preconsolidation stress, σp’

• Relative Density Index, Dr

• Rigidity index, Ir

• Sensitivity, St

• Shear wave velocity, Vs

• Small strain shear modulus, G0

• Soil behaviour type Index, Ic

• SPT N60 and stepped average

• State Parameter

• Undrained Shear Strength, su

• Unit Weight, γ

• Young’s modulus, E

Fence Diagram/Cross Section

Dynamic user-definable fence or cross section reports:

• Choose up to 6 parameters and correlations to display, e.g. qc, qt, Rf, Ic plots

• Soil behaviour type coloured column

• Material graphic column

• Legend for soil behaviour type

• Legend for material graphic


Dissipation Test

Dissipation tests may be analysed using the strain path method (SPM) proposed by Houlsby and Teh 1988.

Dissipation tests carried out in overconsolidated soils maybe corrected using the square root time method, as proposed in Sully et al. 1999, and short tests may be extrapolated forward to estimate tx, (e.g. t50).

Data Correction Tool

Allows for one-off corrections of data

Example applications:• Offset one parameter a fixed depth, e.g. offset sleeve

friction for many tests in one process

• Re-zero the depth if 0 depth is not the ground surface

• Apply calibrations to a parameter defined by a formula

• Correct depth for inclination
