深基坑支护案例分析及变形监测要点

The Case Analysis and Deformation Monitoring Points of Deep Foundation Pit Supporting

某工程的深基坑在原有建筑和城市交通要道的附近，工程地质条件很差，基坑围护的难度较高，安全性难以保障。故选用了多种围护手段紧密结合的支护形式，同时对结构安全及设计参数进行了严格的监测处理。

The deep foundation pit of a project is near the or-iginal buildings and urban roads. The engineering geological condition is very poor, the difficulty of the foundation pit en-closure is higher, and the safety is difficult to guarantee. Ther-efore, the author choose a variety of means closely with supp-orting form and carries on the strict monitoring treatment to the structure safety and design parameters at the same time.
