摘要: 为探测特高压输电通道地表形变,定量评价杆塔受损状况,本文以163幅Sentinel-1A遥感影像为数据源,采用MT-InSAR技术,对穿越河南省三门峡市的灵绍线与陕武线特高压输电通道地表形变进行了解译,构建了任意时间地表累计沉降计算模型,统一了MT-InSAR和水准两种监测数据的时间基准,通过Kriging插值算法实现了MT-InSAR和水准监测数据的融合;创建了顾及地下采出空间的曲面拟合求参模型,反演了地表沉陷的计算参数;并依据地表最大倾斜指标对输电线路杆塔的稳定性进行了定量评估。结果表明,MT-InSAR技术能够有效探测特高压输电通道地表形变异常区,输电杆塔产生的沉降和倾斜形变与煤矿地下开采紧密相关。将MT-InSAR和水准数据融合能够有效反演地表沉降的计算参数。采煤沉陷区内LS1130号杆塔超过了地表最大倾斜允许值,需要重建;LS1132、LS1134、SW1006、SW1008 4个杆塔最大倾斜形变位于1.45~2.3 mm/m,产生了较大倾斜,应及时加固维修;其余杆塔最大倾斜形变均在1 mm/m以下。研究成果可为输电线路提供安全预警,也可为采煤沉陷区杆塔受损定量评价与治理提供理论和技术依据。

Abstract: In order to detect the surface deformation under the UHV transmission channel and quantitatively evaluate the damage of the tower,this paper uses 163 Sentinel-1A remote sensing images as the data source,and uses MT-InSAR technology to understand the surface deformation of the Lingshao line and the Shanwu line UHV transmission channel crossing Sanmenxia city,Henan province.The calculation model of surface cumulative settlement at any time is constructed,and the time benchmarks of MT-InSAR and leveling monitoring data are unified.The fusion of MT-InSAR and leveling monitoring data is realized by Kriging interpolation algorithm.A surface fitting parameter model considering underground mining space is created,and the calculation parameters of surface subsidence are inverted.According to the maximum inclination index of the surface,the stability of the transmission line tower is quantitatively evaluated.The results show that MT-InSAR technology can effectively detect the abnormal surface deformation area of UHV transmission channel,and the settlement and tilt deformation of transmission tower are closely related to underground mining of coal mine.The fusion of MT-InSAR and leveling data can effectively invert the calculation parameters of surface subsidence.The LS1130 tower in the coal mining subsidence area exceeds the allowable value of the maximum tilt of the surface and needs to be reconstructed; the maximum tilt deformation of the four towers of LS1132,LS1134,SW1006 and SW1008 is between 1.45 and 2.3 mm/m,resulting in a large tilt,which should be strengthened and repaired in time ; the maximum tilt deformation of the remaining towers is below 1 mm/m.The research results can provide safety warning for transmission lines,and also provide theoretical and technical basis for the evaluation and treatment of tower damage in coal mining subsidence area.
