针对施工场地狭窄,无法运用传统方法进行变形观测的情况下,对深基坑的水平位移监测提出了全站仪坐标法。对全站仪坐标法监测水平位移的精度进行分析,通过分析结果与工程实践,验证了对于不同等级要求的基坑水平位移监测,只要选择适当的全站仪进行作业,即能保证精度符合要求,提高作业效率。
針對施工場地狹窄,無法運用傳統方法進行變形觀測的情況下,對深基坑的水平位移鑑測提齣瞭全站儀坐標法。對全站儀坐標法鑑測水平位移的精度進行分析,通過分析結果與工程實踐,驗證瞭對于不同等級要求的基坑水平位移鑑測,隻要選擇適噹的全站儀進行作業,即能保證精度符閤要求,提高作業效率。

It is proposed that the coordinate method should be used as the solution to the problems caused by narrower construction sites where the traditional methods are not applicable.An analysis is carried out on the accuracy of horizontal displacement monitoring by Total Station coordinate method.By engineering practice and results analysis,it verified the requirements for different levels of horizontal displacement of foundation pit.Only if the appropriate operating Total Station was selected,the method can meet the requirements to ensure accuracy and improve operational efficiency.
