摘　　要：文中旨在研究潮汕地区某车站竖向支撑系统,该系统由桩柱板一体结构构成,因此,桩柱板结构在整个开挖过程中的力学性能和稳定性尤为重要。为了实现这一目标,文中采用Plaxis 2D有限元软件模拟对基坑开挖进行了二维建模,并模拟实际施工情况,分析和研究各个开挖步骤下桩柱板结构的力学性能、稳定性和变形情况。The purpose of this paper aims to study the vertical support system of a station in the Chaoshan area,which is composed of a pile column integrated structure.Therefore,the mechanical performance and stability of the pile column slab structure are particularly important throughout the excavation process.In order to achieve this goal,we used Plaxis 2D finite element simulation software to model the excavation of the foundation pit in 2D and simulate the actual construction conditions to analyze and study the mechanical properties,stability and deformation of the pile plate structure under each excavation step.
