On the basis of comprehensive analysis of the characteristics and operating conditions of mountain levees, combined with industry standards and related professional research, a mountain levee safety evaluation system with 17 evaluation indexes was constructed, including rainfall intensity, channel shape, dike material, dike permeability, historical danger, etc. The indexes were weighted subjectively and objectively by improved analytic hierarchy process and CRITIC method based on average difference, and an improved combined weighted cloud model evaluation method was proposed based on game theory. The proposed improved method was applied to the safety evaluation of a mountain levee project in Qingyuan. The calculation and analysis show that the safety score of the mountain levee project is 70.6, and the safety level is basic safety, which is consistent with the actual situation of the project. The reliability and rationality of the levee safety evaluation method proposed in this paper is then verified, and it can be used for the levee safety evaluation in mountain area.
