Abstract：
Depending on foundation pit project for underground garage of Midu Bridge, Hushu South Street, Hangzhou City, through comparison and analysis of monitoring data and calculated results of finite element model, the reasonable simulation method of applying brace pre axial force is proposed and the finite element model suitable for the practical conditions is erected. Through using the suitable models, reasonable suggestions for design and construction on applying brace pre axial force are proposed and can be referenced by similar projects.
