Abstract：Water and mud burst occurs commonly in karst region,which causes many problems to the engi-neering construction of subway station in the water-rich karst area and the fault rupture zone.It is of great importance to the design and construction of subway station excavation by investigating of the characteristics of the karst development and water burst.In this paper,the treatment of karst water burst in the deep pit of a subway station in Guiyang is presented.Based on site investigation and theoretical analysis,the character-istics of karst development and water burst in the subway station was studied and summarized with the aid of 3D geological software.The spatial relationship between the karst,the fault zone and the subway is estab-lished and represented by 3D geological model.This study can be very useful to the design and construction of similar subway station in terms of karst hydrogeology and the treatment of water burst.
