基于灰色关联度的在役混凝土结构耐久性评估
Durability Evaluation of Concrete Structure Based on Grey Relation Degree
摘要
Abstract
To raise the accuracy and objectivity of concrete structure durability evaluation,we proposed a method based on grey system theory.First,the models with "less data" were developed based on inspection data,and the values of evaluation indexes were normalized by nonlinear mathematical methods replacing traditional linear methods;second,the initial expert weights were improved by using the analytic hierarchy process,and the variable weights were constructed;next,the sample and evaluation indexes were analyzed by the grey system theory,and the concrete structure durability condition was evaluated by the grey relation degree.Finally,the application process of the method was illustrated in a practical engineering case,and the reliability was also proved.The results show that the durability evaluation method of existing concrete structures based on grey relation degree can effectively reduce the influence of subjective factors and expert knowledge on the evaluation results and the calculation process is simple,providing references for practical engineering application.关键词
