This article introduced the method of geological investigation of Nanling Tunnel karst disease,elaborated the tunnel engineering geology conditions,especially the karst water,the karst water power channel and the harm of karst water,and analyzed the cause that produced the karst disease.

Nanling tunnel is a shallow-hurried tunnel where karst develops and geological condition is very complicated.
