FINITE ELEMENT ANALYSIS OF SOIL-PILE INTERFACE UNDER CYCLIC LOADING

The behavior of circular pile has been widely treated considering the loading as a monotonic loading. In practise, the type of the load is varies according to many factors, which pushed us to use cyclic loading. The purpose of this article is to analyze the behavior of the soil-pile interface in calibration chamber under cyclic loading. A finite element analysis, through Plaxis 2D code, is used to realize this study. This paper deals with a new evaluation of the pile response, by taking into account the different pile–soil adhesions. It is found at the level of the friction sleeve that, the shear stress increases when the pile–soil adhesions increases. Further, the lateral friction stress is much more influenced by the friction sleeve roughness.
