Outline
The investigation of earthquake damage shows that the lateral spread of gently inclined soil is a common form of foundation failure. As the concrete pile has a high vertical bearing capacity and shear resistance, and the stone column has a high permeability, which can effectively reduce the degree of liquefaction of the surrounding soil, whether the concrete-stone composite pile can be used as an effective engineering measure to deal with the large lateral deformation of liquefaction in gently inclined soil, its feasibility is worthy of in-depth research. Therefore, the numerical model of liquefiable soil-pile foundation is established based on OpenSees finite element platform, then the reliability of the numerical model is rerified. On this basis, the reinforcement effect of concrete-stone composite pile on inclined liquefaction soil is studied. In addition, the effects of area ratio of core pile and thickness of stone shell on dynamic response of inclined liquefaction soil are discussed. The results show that the concrete-stone composite pile has a significant anti lateral displacement effect, which can effectively reduce the lateral displacement of the surrounding soil and the bending moment of the concrete core pile. When the proportion of concrete core of pile body is about 20% and the proportion of stone shell area is 80%, it is the optimal design scheme.
