由于城市建设用地稀缺,为了建设地铁、地下车库、地下商场等,经常在人口稠密、建筑林立、道路纵横交叉的城市中心区开挖深大基坑。基坑施工过程中,为了减小对周边环境的不利影响,必须控制基坑围护结构的侧向变形。总结了软土地基深基坑常用的围护型式和变形监测项目,结合实测数据分析了不同围护型式的变形规律,指出了不同围护型式的适用范围,对基坑设计及施工单位具有一定的借鉴意义。
Due to the scarcity of land for urban construction, in order to build subways, underground garages, underground shopping malls, etc., deep foundation pits are often excavated in urban centers where densely populated, densely populated and criss-cross roads intersect. In the process of foundation pit construction, in order to reduce the adverse impact on the surrounding environment, the lateral deformation of the retaining structure of foundation pit must be controlled. Summarizes the commonly used envelope and deformation monitoring projects of deep foundation pit in soft soil foundation, analyzes the deformation rules of different envelope types with the measured data, points out the applicable scope of different envelope types, The reference significance.
