超深基坑工程预加轴力施加方法的分析与建议

ANALYSIS AND SUGGESTION ON METHOD OF APPLYING BRACE PRE AXIAL FORCE IN ULTRA-DEEP FOUNDATION PIT CONSTRUCTION

以杭州市湖墅南路密渡桥地下停车库基坑围护工程为依托,将有限元模型计算结果与实测数据对比分析,提出了施加钢支撑预加轴力的合理模拟方法,并建立了适合工程实际的有限元模型。通过对上述有限元模型计算结果的分析,针对施加支撑预加轴力的设计与施工提出了合理建议,可供类似工程参考。

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 models, reasonable suggestions for design and construction on applying Through using the suitable brace pre axial force are proposed and can be referenced by similar projects.
