基于正态云模型的混凝土桥梁耐久性评估

Durability assessment of concrete bridges based on normal cloud model

为了合理地对既有混凝土桥梁耐久性进行评估,提出了正态云和CRITIC法相结合的评估模型。根据混凝土桥梁耐久性的主要影响因素以及表现形式建立相应的评价指标体系,采用CRITIC法对影响混凝土桥梁耐久性因素的权重进行分析计算,利用云模型建立混凝土桥梁耐久性评估指标与模型之间的关联函数。通过实例分析证明,该基于正态云理论的混凝土桥梁评估模型能准确地判断混凝土桥梁的耐久性状态,可为混凝土桥梁的维修加固提供理论依据。

In order to reasonably evaluate the durability of existing concrete bridges,an evaluation model combining normal cloud and CRITIC method is proposed.According to the main influencing factors and manifestations of concrete girder bridge durability,the corresponding evaluation index system is established.The CRITIC method is used to analyze and calculate the weights of the factors affecting the durability of concrete bridges.correlation function between.The example analysis proves that the concrete girder bridge evaluation model based on the normal cloud theory can accurately judge the durability state of the concrete girder bridge,and can provide a theoretical basis for the maintenance and reinforcement of the concrete girder bridge.
