Numerical Analysis of Pile Response to Deep Excavation in Soil Overlying Rock

Much research has been done on pile response to deep excavation construction in soft soil. However, the behavior of the pile and pile groups due to deep excavation in multilayered conditions of soils overlying rock (defined as soil-rock formations in this paper) is still unclear. This study performed a series of 2D numerical studies of pile response due to deep excavation. Firstly, the numerical model was verified through a case history in China and the comparison of computed results to monitoring data showed good agreements. Secondly, the effects on the pile response of several parameters were studied, including stratigraphic distribution, distance to the retaining wall, pile length, excavation depth, and stiffness of retaining wall and pile. The results presented in this study can be used as a first approximation for cases in which the deep excavation is located very near the pile and pile groups.
