Abstract

The slope stability allowed reliable index is 4.2 in specification of rockfill dam for 200 m height, critical slope safety factor of stability is 1.3, but there is not a fitted safety standard for rockfill dam of more than 200 m height and critical slope of this project. Summarizes the failure probability, safety standards and puts forward an acceptable risk criteria of slope (failure probability), ratio safety margin is a method to verify the rationality of risk standards and risk control level of safety factor of slope stability. Allowed reliable index for the slope of rockfill dam with extra height is 4.2 and 3.95, and the corresponding safety factor of the slope stability is 1.35 and 1.4, according to the practical engineering to verify reasonability of safety factor and allowed reliable index of rockfill dam with extra height. The safety control standard of the slope of rockfill dam with extra height should to be improved.
