Analysis of the Effects on Metro Station’s Main Structure Generated by Foundation Pit Support Structure

Abstract:

For the present open cut method is still the main method of the construction of metro stations. Foundation pit support structure and lining structure are composed of three basic side wall structure systems (single wall, compound wall and composite wall). In the calculation of internal force of structure, complex interactions between foundation pit support structures including bored pile and diaphragm wall, and the side wall of main structures are investigated. One form is that the foundation pit support structure and side wall can only deliver pressure and separate partly; another is that they deform together by construction measures. In this paper, the effects on the internal force of main structure influenced by foundation pit support structure are quantitative studied, and the reference resources for optimization design are provided.
