摘要
结合某基坑变形监测项目,从观测墩及觇牌的设计、观测方法、精度估计等方面对基坑水平位移观测进行了介绍,并介绍了利用差异沉降量推算法进行倾斜观测的方法。
Combined with a certain foundation pit of a deformation monitoring project, this paper introduced the foundation pit of horizontal displacement observation from the aspects of the design of observation pillar and the target, observation methods, accuracy assessment, etc. And it introduced the use of differential settlement prediction to carry out the inclination observation.
