对于大直径圆柱壳结构及其土体分别采用壳单元和沿深度分层施加的三维空间弹簧单元进行模拟 ,推演了一种耦合数值分析方法 ,综合考虑了土体特性、土体深度及变形情况等因素。采用壳单元和弹簧单元的耦合数值处理可以有效地模拟大直径圆柱壳结构与土体之间的非线性相互作用机制。通过对实际工程的计算 ,所得到的圆柱壳结构在荷载作用下的受力状态以及位移与变形分布情况等结果均较为理想

Shell element and three dimension spring element applied at different depth in soil are explored to analyze the interaction between soil and cylinder with large diameter. A coupled analysis method is developed to consider the influence of the characteristics of the soil, the depth of the structure in soil and the deflection of the structure. It is proved that this method is very efficient to imitate the nonlinear interaction between soil and cylinder with large diameter through the analysis of an actual project. The results of deflection, displacement and stress of the cylinder under loads are satisfactory.
