Study on Monitoring and Warning System of Karst Water Bursting Disaster in Karst Area

Rely on major projects such as the Shanghai-Kunming high-speed railway, the paper studies the method and system of monitoring and warning of Karst water bursting disasters in high risk tunnel. Taking water pressure, water inflow and surrounding rock deformation as warning indicators, the paper studies the classification of warning grade and warning index of Karst water bursting disaster. With the stacking and coupling analysis between monitoring data of warning indexes and conclusion of risk assessment, Karst water bursting disaster during tunnel construction monitoring and warning system is established. The feasibility and practicability of this method are verified by case analysis. It has important reference value for the construction and design of similar tunnel engineering.
