摘要
针对基坑施工安全问题愈发普遍的现象,本文阐述了全站仪在基坑施工过程三维坐标监测的方法,进行了平面位移和沉降观测的精度分析,通过工程实例应用及分析结果,确定了全站仪基坑变形监测降低误差的方法,验证了不同测距精度的全站仪对不同等级要求基坑变形监测的可行性,降低了基坑施工发生安全事故的概率。
In view of the foundation excavation construction safety problem is becoming more common. This paper elaborated the total station in foundation excavation construction process of 3D coordinate monitoring method,conducted precision analysis of plane displacement and settlement observation,by engineering examples and analysis results,determined the total station foundation pit deformation monitoring effectively reduce the error of the method,verified that the different ranging accuracy total stations for different levels of claim pit deformation feasibility,reduced the probability of foundation pit construction safety accidents.
