FUZZY COMPREHENSIVE EVALUATION OF THE GEOLOGICAL HAZARDS ON HILL-TYPE RESERVOIRS——TAKING THE CHENGXIN RESERVOIR OF XIFENG COUNTY AS AN EXAMPLE

The author evaluated the geological hazards in hill-type reservoirs with the fuzzy comprehensive evaluation,taking the Chengxin reservoir of Xifeng County as an example,established the index systems of the geological hazard risk evaluation for hill-type reservoirs,used the analytic hierarchy process to determine weights of evaluation factors,evaluated quantitatively the risk with fuzzy comprehensive evaluation,deduced the evaluation results according to the principle of the maximum subordination principle to every unit.
