| 摘 要： | 基于m法对弹性土抗力的假设,结合有限元基本原理,考虑桩土相互作用后横向受力桩的综合刚度——通过将桩侧土的刚度与桩身刚度叠加进行分析.结合算例计算出桩身变位和内力,并与m法的幂级数解计算结果相比较.综合刚度有限元法的算法简洁,适用范围广,便于编制程序计算和控制,精度也能满足工程要求.

| Abstract: | On the basis of m method assumption of elastic soil resistance and the basic principles of finite element method,the integrated stiffness taking into account the interaction of pile-soil is derived,and it is analysed by superimposing the resistance stiffness of soil around the pile onto stiffness of pile.By instance,the displacements and internal force are analyzed by this finite element method with integrated stiffness,and they are compared with those calculated by power series method based on the same m m... |
