基坑开挖过程中围护支撑应力的监测方法

Monitoring Methods of Support Stress of Enclosure Structures in Excavation of a Foundation Pit

在杭州市西湖文化广场基坑围护支撑应力的监测中,提出了温度影响修正系数、温度应力的计算方法及采用实测的混凝土弹性模量换算应力。工程实测验证了该测试方法的合理性。

During monitoring the support stress of enclosure structures of the foundation pit of Hangzhou Xihu Lake Culture Plaza, authors provided calculation methods of the temperature influence correction coefficient and the temperature stress, and a method of adopting the measured concrete elastic ratio to calculate stress. They testified the rationality of this method in practical projects.
