基于层次分析法的梁桥加固施工质量模糊综合评价方法

摘要

针对梁桥加固结构复杂、病害多样、施工工艺多导致的加固施工质量评价困难等问题，综合考虑实际情况、规范要求，将其归纳为下部结构、上部结构、桥面系、附属工程等4个方面的因素，选取基础、支座、主要承重结构等15个指标，借鉴层次分析法的思想，确定了指标权重与隶属度，给出了评价体系的求解方法与输出形式，建立梁桥加固多层次模糊综合评价方法。结合某梁桥加固工程实例，介绍了该方法的应用。%To solve difficult problems of complex structure of bridge reinforcement,variety of disea-ses,and complexity of construction technology,four kinds of factors,such as the substructure,su-perstructure,deck system,and appurtenant are summarized.1 5 indexes are selected,such as the foundation,bearings and main structure and so on.The ideas of the analytic hierarchy process (AHP) are used to determine the index weight and membership degree,and establish the multi-level fuzzy comprehensive evaluation method of bridge reinforcement.The solving method and the output are also given.With an instance of a girder bridge reinforcement proj ect this method is verified.
