摘要
某基坑工程位于南宁市五象区,开挖深度约14.5 m,与现状民宅距离约8 m,属一级基坑。根据地质情况采用了不同的放坡围护形式,并对深基坑边坡分步开挖过程中的坡体变形进行了仿真分析,直观形象地刻画了边坡位移变化的特征。得到一些对基坑工程设计和施工有实际意义的结论 ,可对放坡开挖深基坑有一定的指导意义。
With the background of some foundation pit project in Wuxiang District,Nanning,it belongs to Class A foundation pit,because its excavation depth is about 14.5 m and the distance from current residence areas is approximately 8 m.Different sloping enclosure types are adopted according to different geological conditions,and moreover,the slope deformation is made a simulation analysis during the process of its stepby-step excavation to describe the features of slope displacement visually.Several practical meaningful conclusions to foundation pit project design & construction are obtained,which can provide references for sloping & excavation of similar projects.
