Comprehensive Evaluation Method for Deformation Safety of Dam Based on Attribute Recognition and Combined Weighting
In order to effectively deal with the issue of orderly segmentation of multiple attributes in dam deformation safety evaluation,a comprehensive evaluation method for deformation safety of dam based on attribute recognition and combination weighting was proposed by comprehensively considering the principle of minimum cost,confidence criteria and level eigenvalue.According to the characteristics and causes of dam deformation,the model selected crack,vertical displacement and horizontal displacement as the safety evaluation indexes of dam deformation.The K-S method was used to test the mathematical distribution of evaluation indicators.The safety monitoring indexes were formulated,based on the typical small probability method and the 3σ principle.Furthermore,the improved game theory was introduced to combine analytic hierarchy process and entropy weight method and the optimal combination weighting was carried out.Under the framework of attribute mathematics theory,a comprehensive evaluation method of dam deformation safety was built.The established method and set pair a-nalysis method were applied to engineering examples for verification.The results show that the model has good feasibility and applicability.
