摘要:

针对桥梁综合技术状况评估中常权综合理论和模糊评估理论的局限性,提出基于局部变权原理和云理论的桥梁评估方法.分析桥梁评估研究中各阶段权重变化的特点,建立局部变权模型,通过评估实例确定局部变权模型参数的取值.根据现行行业规范,确定正态云模型的有效论域,根据有效论域分别计算云模型的期望值、熵和超熵,通过前向云发生器生成正态云图.以某悬索桥为评估实例,验证了该方法的可行性和适用性.结果表明,采用该评估方法得到的桥梁评估结果与实际桥梁采用的维修对策相符.

Abstract:

A bridge assessment approach was proposed based on the local variable weight principle and the cloud theory in order to overcome the disadvantages of the constant weight comprehensive assessment and the fuzzy assessment methods. The local variable weight model was established according to the analysis of the variable-weight character in bridge assessment. The parameters of the local variable weight model were determined based on the assessment instances. The effective domain of normal cloud model was decided by the current codes. Mathematical expectation, entropy and hyper entropy were calculated based on the effective domain. The normal cloud chart was generated by the forward cloud transformation. A suspension bridge was taken as an example to prove the feasibility and practicability of the proposed method. The results of the proposed method accorded with the actual maintenance strategy.
