某深基坑支护工程监测方案及实施

Monitoring Scheme and Implementation of Support Project for a Deep Foundation Pit

深基坑工程对周围环境破坏性大,造成的损失也大,各级建设管理部门都将之列为管理的重点。为及时了解基坑支护结构的变形情况,提前采取措施,防患于未然,该文通过对某深度为9m的基坑监测方案进行描述,阐述了如何制定监测项目、监测等级、监测精度及方法等,为类似工程制定监测方案提供依据。

The deep foundation pit engineering is very destructive to the surrounding environment and causes great losses. Construction management departments at all levels have listed it as the focus of management. In order to understand the deformation of the support structure for foundation pits in time to take preventive measures in advance. This paper described a monitoring scheme for a foundation pit with a depth of 9 m, and elaborated how to formulate monitoring project, moni-toring level, monitoring accuracy, and methods, etc., providing a basis for similar projects to develop monitoring programs.
