时域反射测试技术在基坑变形监测中的应用

Application of Excavation Deformation Based on Time Domain Reflector

基坑位移的测量工作是工程建设和工后的一项重点工作,见于基坑深部位移监测的复杂性,采用时域反射测试技术在基坑监测方面的应用。通过工程算例的计算结果与监测数据对比表明:时域反射技术能够得到基坑土体深部剪切位移的分布和潜在滑动面的位置,这为工程实践提供了可资用的指导。

It is key process for pit foundation to be gained deformation during the whole engineering construction.The time domain reflector is applied for deep displacement,which is taking on complicated and difficult fact.Comparisons between the calculated datum and testing datum show the deep shear displacement and location of sliding face are obtained by time domain reflector,it can serve as engineering projects.
