地铁车站深基坑施工中的变形监测研究

Study on deformation monitoring of deep foundation pit construction in Metro Station

控制基坑变形是地铁的安全运行重要保证,因此在施工中要对地铁基坑变形进行监测与控制。地铁深基坑变形监测一般可通过坑底土体变形、围护墙体变形、墙后土体沉降变形的监测来实现。在施工中,应遵循边挖边护的原则,在开挖的同时,做好支护工作。

To control the deformation of foundation pit is an important guarantee for the safe operation of the subway, so in the construction of subway foundation pit deformation monitoring and control. Deformation monitoring of deep foundation pit of subway station can be through the bottom of the excavation deformation, retaining wall deformation, wall soil settlement deformation monitoring to achieve. In the construction, should follow the principle of protecting the digging, excavation in at the same time, do a good job of supporting.
