摘　　要：通过地质-地球物理特征分析、地球物理正演数值模拟分析和实际电性结构分析,得到城市地下“管涌”的电性结构特征是电阻率梯级带聚变区域,低阻区域推断为充填水“管涌”通道,高阻区推断为干燥或未充填水“管涌”通道;电阻率梯级带缓变区域,低阻区和高阻区推断为潜在的“管涌”通道。由于地球物理成果的反演计算具有多解性,建议结合地质资料进行综合解析。运用高密度电法调查城市地下“管涌”空间分布规律,可提前解决存在的安全隐患问题,对城市地下空间的开发、治理、综合利用具有很大的指导意义。Through the analysis of geological and geophysical characteristics,geophysical forward numerical simulation and actual electrical structure analysis,it is concluded that the electrical structure characteristics of urban underground"piping"are resistivity cascade zone fusion area,low resistance area is inferred to be filled water"piping"channel,high resistance area is inferred to be dry or unfilled water""piping"channel.The resistivity cascade zone with slow variation,low resistance zone and high resistance zone are inferred as potential"surge"channels.Because the inversion estimation of geophysical results has multiple solutions,it is suggested to combine geological data for comprehensive analysis.Therefore,the application of high-density electrical method to investigate the spatial distribution of urban underground"piping"has great guiding significance for solving the existing safety problems in advance,as well as for the development,management and comprehensive utilization of urban underground space.
