摘要
在电力工程选址与施工、运营维护与监控的过程中,电力设施的地基变形、位移监测是一项十分重要的内容。当前,InSAR技术在电力设施的工程应用较少,本文以某风电场为研究对象,采用16期Sentinel-1A数据开展InSAR技术在电力设施地表形变监测中的应用研究。通过本文的研究工作,获取了风电场在2015年5月到12月期间产生的地表形变。监测结果显示,风电场风车所在区域存在明显的地表形变,最大形变速率达到-360 mm/a。时序形变监测结果显示,地表形变存在明显的两种不同特征,这跟养殖场地下水的抽取有关,初步证明了InSAR技术在电力设施地基稳定性监测的有效性。
In the process of power engineering construction, operation maintenance and site selection, Deformation monitoring of the power facilities is a very important content. Currently, the InSAR technology has been not well applied in power facilities due to its technically difficult and data limitation. In this paper, the research on the deformation monitoring of power facility based on InSAR technology is carried out on a wind farm. The 16 period datas of Sentinel-1 A have been used to obtain the surface deformation of the Wind farm during May 2015 to December 2015. The analysis results showed that the surface deformation exists in the areas of wind farm obviously and the maximum deformation rate has reached-360 mm/a. Two different characteristics of the surface deformation caused by the extraction of groundwater have been observed base on the results of time series deformation. The results have proved the effectiveness of the InSAR technique in monitoring of foundation stability on power facilities.
