Abstract：Research purposes: Aiming to the presence of great loss and casualties caused by frequent geological hazard of water － bursting during large tunnel construction in karst zone，the occurrence mechanism and prevention of water －bursting hazard for karst Tunnel had been studied with the plate theory and shear failure theory for the purpose of knowing the occurrence conditions of water － bursting，taking the prevention measures and working out the construction principle．
Research conclusions: There must be four basic conditions for occurrence of water － bursting． The rock plate is easy to become slack，resulting in water － bursting due to the change of the stress field of rock mass and the effect of water pressure in the tunnel． The principle of draining water to cut the water pressure，conducting the advanced support，and ponding muddy water along with draining clean water should be followed in karst tunnel construction．
