                    害如变形、裂缝、渗漏水等,而电力隧道工作井具有较复杂的水土环境与电磁干扰等不利因素,采用正常的巡
                    查手段很难在早期发现结构的损伤与病害,因而对结构的正常服役与安全带来了极大的挑战。以上海杨树浦

                    查,并对雷达数据进行了去噪和解析,分析了产生结构病害的原因以及后续的封堵和修复措施。结果表明:采
                    用高频探地雷达能够较好地捕捉到地下结构的脱空腔体与地下水分布情况,给后期的维修指明了方向。本研

                    Abstract:Ultra-deep electric power wells of power cable in soft soil areas are subjected to large soil and water



                    pressures and loads,and after long-term service,various damages such as deformation,cracks,seepage and wa⁃

                    ter leakage often occur. However,electric power wells are faced with unfavorable factors such as complex soil and


                    water environment and electromagnetic interference,and it is difficult to detect structural damages early by nor⁃

                    mal  inspection  methods.  Therefore,the  normal  service  of  the  structure  and  the  safety  of  the  structure  have
                    brought  great  challenges.  Taking  the  No.  1  working  well  of  cross-river  tunnel  of  Yangshupu  Power  Plant  in
                    Shanghai as the research object,the high-frequency ground penetrating radar(GPR)developed by Tongji Univer⁃


                    sity was used to conduct a comprehensive and detailed inspection on the long-term leakage of the structure,de-


                    noising and analyzing the radar data,and analyzing the causes of the structural diseases as well as the subsequent
                    plugging and repair measures. The use of high frequency GPR can better capture the cavity and groundwater distri⁃


                    bution of underground structure,which points out the direction for later maintenance,and can provide reference
                    for similar structural damage detection in the future.
