【Abstract】 This paper described a three dimensional finite element approach for analyzing the behavior of large diameter cylindrical wharf structures.The cylinder was represented by non-conforming elements with eight nodes and the interaction between soil and cylinder was simulated by three dimensional rigid plastic interface elements. Based on a practice case of large diameter cylindrical wharf structure, study was preformed on the behavior of the interaction between cylinder and soil with different factors such as the ratio of cylinder stiffness to the modulus of deformation of soil, soil characteristics of foundation, filled soil characteristics, the ratio of cylinder height to diameter and the ratio of cylinder height to embedding depth.更多还原
