摘  要:以高密度电阻率法探测原理及反演计算方法为基础,借助场地试验验证了高密度电阻率法在未知地层勘测中的有效性。并利用高密度电阻率法实地勘测了拟建XC高压输电线路的途经地区,根据各测线对应地层电阻率的分布特点进行分析,认为探测区域范围内可能存在未填充的采空区。该探测结果可为设计部门提供输电线路择址参考,以规避采空区对输电线路安全运行造成的威胁。Based on the detection principle of the high density resistivity method and its inversion calculation result,the effectiveness of the high density resistivity method in an unknown strata is verified by the field experiment in this paper.Also,the mining area of the transmission line corridor is detected by high density electricity method.According to the characteristics of lateral lines corresponding to the formation resistivity distribution of underground,maybe there was a unfilled mined-out area in detection area.The detection results can provide line path selected reference for design department,which can avoid the safe risk of the mining area when the line is operating.
