Abstract:

According to the current situation of the early warning system in our country and the characteristic of water inrush in karst tunnels, the early warning disaster prevention system was discussed in the aspects of early warning mechanism,which consisted of early warning organization systems, operation mechanism and warning insurances, and emergency response planning and drilling. The four-color warning mechanism was proposed for the first time in our country and the emergency response planning and drilling were consequently improved. It has been successfully applied in the Wuchiba and Qiyueshan Tunnels of Hurongxi Highway and it can be used in preventing water inrush disaster in high-risk tunnels in karst zones in the future.

Key words: karst tunnel; water inrush; early warning mechanism; early warning and disaster prevention system; emergency rescue
