The method for improving the accuracy of risk-based assessment of the tailings dam of the reservoir water level

The present invention relates to a method of improving the accuracy of risk assessment is based on the tailings dam reservoir water level. The method includes: one pair of reservoir water level of the dam and risk status information acquisition and real-time pre-processing; 2 function of establishing complex relationship among the possible risk dam reservoir water level and the state; 3 based on the use of similar. weighted measure of the fusion of a plurality of function fusion process; 4 fusion process convex function, the possibility of using the obtained mean and variance value interval risk status of the dam to dam risk assessment and risk publish grade. The tailings dam to improve accuracy of risk assessment method of the present invention, it has the advantage of high accuracy, and to facilitate wide engineering application implemented on the module system.
