Research on the Internal Force and Deformation of the Pile Plate Structure in the Construction of Subway Station by Cover-and-dig Reverse Method
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 deform-ation of the pile plate structure under each excavation step.
