摘　　要：引水隧道施工中屡次发生坍塌,用探地雷达对衬砌质量及地质情况进行探测。经数据反演,清晰勾画出衬砌背后空洞、松散堆积体分布范围,地下水的赋存特征,为治理事故提供切实可靠依据。The collapse takes place frequently in the construction of drainage tunnel.The liner quality and geological situation are explored with the geological radar.According to the data inversion,the distribution range of hole,loose aggregate behind the liner and underground water are outlined in order to provide the reliable foundation for the accident processing.

关 键 词：隧道坍塌 扰动岩土体范围 隧道衬砌施工质量 EH4方法 地质雷达探测
