基于模糊综合评判法的桥梁监管评价体系研究

Study on Appraisal System for Bridge Supervision Based on Fuzzy Comprehensive Evaluation Method

桥梁监管是一项较为复杂的综合性工作,其影响因素十分复杂。桥梁监管评价过程中存在大量的随机性和模糊性,很难找出多为状态函数之间的函数映射关系。对这样复杂的非线性大系统问题,采用模糊数学方法,把定性描述转化为定量的数学语言,对桥梁的监管系统的各个因素进行全面综合评判,建立合理的评价体系,为桥梁施工过程的安全管理和事故防治提供了依据。

Bridge supervision is a complex and comprehensive task, which has very complex influencing factors. It is difficult to find a function mapping relation among multi-dimensional functions due to a large amount of randomness and fuzzi- ness occurring during the process of bridge supervision assessment. For so complex and nonlinear large scale system issue,a reasonable evaluation system is established to evaluate comprehensively each factor of bridge supervision system by the fuzzy mathematics method transferring qualitative description to quantitative mathematics language. This model can provide a general reference for the safety management and accident prevention of bridge construction.
