摘要
针对基坑工程施工场地狭窄、周围基准点均存在变形等情况,常规的测量方法无法进行基坑水平位移监测。为此提出自由设站法对基坑进行水平位移观测技术。通过分析自由设站的原理和观测精度,得出自由设站法的技术要求。并以实际工程为例,说明该方法对基坑进行水平位移监测完全满足要求,具有较好的实用价值。
It is proposed that the free-station positioning method should be used as the solution to the problems caused by narrower construction sites of Foundation pits and the instability of control point of arounding the foundation pit. Through analyzing the principle of free-station positioning and monitoring precision,the technical requirements of free-station positioning can be got. And taking practical engineering for example,it is shown that the method of horizontal displacement monitoring for pits meets standardized requirements completely and has good practical value.
