土与复合桩支护结构变形破坏分析

Deformation and Failure Analysis for Soil and Multiple Piles Retaining Structure

对深基坑在7种不同复合桩支护结构条件下开挖分别进行了弹塑性有限元模拟，根据计算结果分析了土与复合桩支护结构在不同条件下的变形特点和破坏模式．

Elastic-plastic FEM is used to respectively simulate the pit excavation under 7 different conditions of multiple piles retaining structure based on the engineering practice. The deformation features and failure mechanism of multiple piles retaining structure under different conditions are analyzed on the basis of numerical simulation results.
