采用经纬仪的变电站地基沉降监测分析法

Monitoring and Analysis Method of Foundation Settlement for Substation Based on Theodolite

摘要:

针对地基不均匀沉降对丹巴变电站造成的影响，以及目前的监测分析方法存在过于复杂难以在高海拔、地质 条件恶劣地方实际应用的现状，提出了一种采用经纬仪的监测分析法。首先采用经纬仪进行监测，然后由两点对比 法对监测结果进行分析，通过分析结果判断不均匀沉降的发展趋势，最后对沉降的可能原因进行了分析并提出管控 措施，有效地防止了二次灾害的发生，证明了该方法的有效性和实用性。

Abstract:

Aiming at the impact of uneven settlement of foundation in Danba substation and the situation that the current monitoring and analysis methods are too complex to be applied to the areas with high altitude and poor geological condition，a monitoring and analysis method using theodolite is proposed． Firstly，the theodolite is used for monitoring，and then the monitoring results are analyzed based on two － point comparison method，and the development trend of uneven settlement is judged by the analysis results． Finally，the possible causes of settlement are analyzed and the control measures are put forward，which can effectively prevent the occurrence of secondary hazard． So it proves the validity and practicability of the proposed method．
