深基坑支护结构的三维杆系有限元分析

3D pole system FEM analysis for bracing structure of deep foundation pit

根据深基坑支护系统中支护桩－支撑－土的共同作用特征建立了三维杆系有限元分析模型，该模型不仅能够描述支护结构的空间效应和角效应，而且可以通过计算直接给出设计所需的信息，实例分析结果验证了模型的适用性和有效性。

According to the characteristics of the pile-support-soil joint action in the deep foundation pit support, the 3D bracing structure FEM analysis model was set up. Not only the space effect and corner effect can be described in the model, but also the design information of bracing structure can be gained directly from the calculation. Through a example, the effectiveness of the model is verified.
