兰州某基坑及周边建筑物变形监测分析

Deformation monitoring analysis of a foundation pit and surrounding buildings in Lanzhou

以兰州某基坑工程为背景,通过对该基坑和周边建筑的监测,分析基坑和周边建筑的变形规律,发现基坑及其周边建筑水平位移和竖向位移变化由大减小,直至稳定;基坑变形大于周边建筑变形;周边建筑的位移说明基坑施工确实会对周边建筑和道路有着不可忽略的影响,因此加强对基坑周边的变形监测与控制将是安全控制,及时预防事故发生。

Based on a foundation pit project in Lanzhou, this paper analyzes the deformation law of foundation pit and surrounding buildings by monitoring the foundation pit and surrounding buildings, and finds that the horizontal and vertical displacement change of foundation pit and surrounding buildings decreases greatly until they become stable. The deformation of foundation pit is greater than that of surrounding buildings. The displacement of surrounding buildings indicates that foundation pit construction does have certain influence on surrounding buildings and roads, so it is necessary to strengthen the deformation monitoring and control around foundation pits to prevent accidents in time.
