某深基坑支护换撑监测

Support Replacement Monitoring About Certain Deep Foundation Pit Works

详细阐述了用电阻应变片对某深基坑支护换撑钢管进行多测点、远距离、复杂施工条件下应变长期观测实验的方法,分析了影响长期应变观测的主要因素,论证了消除这些因素应采取的技术措施;通过现场监测,验证设计,弥补现有计算理论的不足,指导施工。

A long term measuring method of strain to steel tubes replaced certain deep foundation pit support that involves multi-measuring points, long distance, and the surroundings of complex construction,which is expounded in detail. The main factors affecting the long-term strain measurement are analysed, some corresponding measures are proposed; Using the actual monitoring datas to test the design, make up the defects of present calculation theories,guide the construction.
