深基坑“T”型地下连续墙应力监测分析

Monitoring Analysis in Stress of “T” Diaphragm Wall in Deep Foundation Pit

根据上海某工程深基坑"T"型截面地下连续墙安全监测数据,修正温度变化对振弦式钢筋计应力测值的影响,通过计算分析地连墙不同截面的应力规律并计算对应的弯矩及轴力值,得出了一些结论和建议,对类似工程有一定借鉴作用。

Basted on the monitoring data of a deep foundation pit adopted the ＂T＂ Diaphragm wall, this paper illustrates the temperature effect on steel bar gauge measurement, of the ＂T＂ Diaphragm wall, and provides amendment coefficients of temperature effect. Through analysis the law of the ＂T＂ Diaphragm wall stress in different sections and the corresponding values of moment and axial force, some conclusions and recommendations are given for the similar engineering projects.
