Abstract:
The development of Karst is harmful to the shallow buried tunnel in limestone distribution region,which is mainly characterised as the tumnel leakage caused by rain or groundwater. In this study, illustrated bythe case of Pishuang’ ao tunnel of Beijing-Zhuhai expressway in Guangdong provinee, high-density eleetricalmethod is applied to the detection of karst leakage passage of tunnel survey area. The deteclion results are con-sistent with the ground investigation of actual geologieal bodies ( ie , karst collapses), which verily the feasibil.ity and aeeuraey of high-density eleetrieal method in the leakage passage detection of karst region.
