Abstract:

The phenomenon of land landing in many areas and roads of the of the

Ajdabia City, the land landing is a vertical or horizontal movement of

the surface of the earth, arising as a result of the imbalance of the

static balance of the surface layers, and may occur gradually and

inconceivably or suddenly. This movement leads to destruction of

engineering facilities, collapse of dams and bridges and the

destruction of infrastructure such as water pipes, sewage, roads and

etc. Land landing occurs as a result of natural causes such as

dissolution of some rocks by torrents, running water, soil weakness or

human factors such as water extraction or damage to sewage and

drinking water networks. This study was conducted to assess the

causes and risks of land landing and how to treat them

This study was based on the theoretical aspect in terms of data

collection from the references, periodicals and previous projects in the

city. A practical aspect is the follow-up of some projects and the

collection of some samples to determine the type and characteristics of

the rocks. In this study it is clear that the cause of this phenomenon is

the result of the processes of dissolving of the soil and limestone rocks

caused by the erosion of sewage and drinking water, which requires

immediate intervention to remedy it

The study recommended digging stones and injecting them with

concrete. The main collapse will be filled with stones and soil. The

sewer pipe will be repaired and repaired in a way that prevents the

leakage of water or the transfer of water to another place. And the use

of geological radar to study the phenomena of landfall
