结合柱列式悬臂桩支护的工程实例 ,利用有限元法对桩身内力和变形进行了全过程分析 ,并对基坑开挖过程中支护结构的内力和变形进行了监测 ,对比理论分析和实验结果表明 ,有限元法比传统的极限平衡法更符合实际 .
Combined with the engineering examples of column-type cantilever pile support, the whole process of pile internal force and deformation is analyzed by finite element method, and the internal force and deformation of the supporting structure during foundation pit excavation are monitored. The experimental results show that the finite element method is more practical than the traditional limit equilibrium method.
