摘要 鉴于土体含水量对基坑支护结构受力特性的重要影响,结合实际基坑工程,首先利用三轴试验,测得土体在不同含水量情况下的物理力学参数.而后,应用PLAXIS软件建立了有限元分析模型,进行了基坑支护结构受力特性的数值模拟计算,得出了含水量对基坑支护结构受力的影响特性与规律. Because of the important influence of soil water content on the retaining structure bearing characteristics of foundation pits, combined with real foundation pit engineering, physical and mechanical parameters of different water content soils are experimented through triaxial test firstly in this paper. Then the finite element analysis model is established using PLAXIS software. The numerical simulation calculation of the retaining structure beating characteristics of foundation pits is done. The influence characteristics and the laws of soil water content on the retaining structure bearing of foundation pits are put forward.
