摘要：The construction of urban metro in high-risk karst areas is different from that of highway or railway tunnel in many ways, such as having a great threat to the project stability, prone to induce secondary geological disaster, damaging the surrounding existing structures and being vulnerable. Based on the analysis of geological water level of internal and external tunnel project and various geophysical prospecting, it puts forward a method to explore the geological disaster seepage channel distribution regularity about urban metro in karst areas in an effective and accurate way. And the implementation and comprehensive analytic process concerning this method are covered in detail, which is exemplified by the geological disaster predication and seepage channel exploration of Yaman interval in urban Rail Line 1, Guiyang city. Then the key technology for comprehensive treatment towards seepage channel of karst tunnel is proposed and further verifying its effectiveness by utilizing numerical simulation software.
