摘　　要：随着国内城市建设发展迅猛,特别是大型城市市区内的深基坑工程,由于各类商业、住宅、道路、地铁等建构筑物密集,深基坑的开挖引起的卸荷效应以及开挖所导致的基坑外水位下降都将引起周边地表及深层土体产生较大位移变形,进而会影响到周边建构筑物的使用安全,本文探讨总结了几种地下连续墙成槽阶段能减少土体挠动的微挠动控制方法,为类似工程施工提供相应的措施方案。With the rapid development of urban construction in China,especially the deep excavation projects in large urban areas,due to the dense construction of various commercial,residential,road,subway and other buildings,the unloading effect caused by the excavation of deep excavation and the decrease in water level outside the excavation will cause significant displacement and deformation of the surrounding surface and deep soil,which will affect the safety of the surrounding buildings.This article explores and summarizes several micro deflection control methods that can reduce soil deflection during the trenching stage of underground continuous walls,and provides corresponding measures and solutions for similar engineering construction.
