ترجمة الملخص

This work consists, on one hand, treatment of geotechnical parameters marly formations in the Sahel of Algiers where problems of instability (cracking of walls, foundations laid bare, landslides ... etc...) Were observed in El-Achour and Dely Brahim region, and secondly, to carry out a numerical analysis using the Plaxis code 8.2 of soil-structure interaction (R Building 5 in our case). This treatment is based on the analysis and interpretation of geotechnical parameters of marl Plaisancian which constitute the subgrade on which the development of the city is headed. The statistical analyzes of different geotechnical study showed that these parameters are influenced by the marl deterioration due to contact with the atmosphere which reduces their resistance causing stability problems due to a very high degree of swelling and the surface which decreases as a function of depth, and slow movements, which can be accelerated by the triggering factors. This led us to distinguish three levels of marl unit where highly weathered, cracked and extremely swelling which has a thickness observed generally ranges from 0 to 5m, a unit of marl weakly to moderately altered means swelling and sometimes cracked with a thickness between 5 and 10m and last unit very hard and rarely swelling that may occur beyond 10m deep sound marl. Numerical analysis of soil-structure interaction for two types of loads (static and dynamic load) with the use of two foundation systems (single and Raft Raft-piles) has to conclude that the structure established (building) in the study area is characterized by high seismicity by RPA 2003 will be stability vis-à-vis the dynamic loads with the use of Raft-piles system that seems to be the worst case.
