在施工过程中,建筑物不可避免地会产生一定的水平位移、倾斜位移、沉降位移、挠度和裂缝,严重者甚至会危及建筑物的安全,造成重大的经济损失。因此,基坑的变形监测与预报是建筑施工中不可或缺的重要环节。本文通过具体案例详细介绍了基坑变形监测的设计、点位的布设、观测及观测频次、数据处理及数据分析等内容,并介绍了基坑变形监测的特点,为今后类似的工程项目提供借鉴。 During the construction process, the buildings will inevitably have some horizontal displacement, tilt displacement, settlement displacement, deflection and cracks. In serious cases, they will endanger the safety of buildings and cause significant economic losses. Therefore, the deformation monitoring and prediction of foundation pit is an indispensable and important link in building construction. In this paper, the design of foundation pit deformation monitoring, the layout of points, the observation and observation frequency, data processing and data analysis are introduced in detail in this paper, and the characteristics of deformation monitoring of foundation pit are introduced, providing reference for similar projects in the future. .
