Abstract: Soil-structure interaction refers to the interaction between a structure, its foundation and the subsoil. As the term soil-structure interaction covers a broad field, the work presented in this paper will be berestricted to the analysis of pit or piled-pit foundations under static loading. Piled-raft is a composite structure which consists of three elements: pile, raft and supporting soil. Loads applied to the raft are transferred to the soil through the piles. Therefore, it is necessary to take into account the interaction between the three elements. Four different types of interaction have to be considered in the analysis. In this paper, we discuss the interaction mechanism for piled-raft foundations and the use of finite layer technique for calculating interaction factors.
