摘要
在灰岩分布区岩溶的发育对浅埋隧道危害极大,主要表现为降雨或者地下水引起的隧道渗漏.以京珠高速广东段媲双坳隧道为例,应用高密度电法对隧道调查区内岩溶渗透通道进行了探查.探测结果与地面调查所探查的岩溶塌陷等实际地质体相吻合,验证了高密度电法在岩溶地区渗漏通道探查中可行性和准确性.
The development of Karst is harmful to the shallow buried tunnel in limestone distribution region,which is mainly characterised as the tunnel leakage caused by rain or groundwater.In this study,illustrated by the case of Pishuang＇ ao tunnel of Beijing-Zhuhai expressway in Guangdong province,high-density electrical method is applied to the detection of karst leakage passage of tunnel survey area.The detection results are consistent with the ground investigation of actual geological bodies （ie,karst collapses）,which verify the feasibility and accuracy of high-density electrical method in the leakage passage detection of karst region.
