【摘要】：桥梁是交通的咽喉，在整个交通运输行业有着举足轻重的作用。近年来，我国桥梁工程建设取得了举世瞩目的进步，然而随着交通事业的发展和在役桥梁使用年限的不断增加，桥梁的病害问题也日益严重，很多桥梁甚至已经成为危桥，因此桥梁养护管理工作也就变的益发重要。本文介绍了国内外桥梁管理系统和桥梁管理系统结构的发展和研究情况；利用AHP结合专家咨询的方法建立了桥梁缺损情况评价模型来评价桥梁缺损技术状况，利用模糊综合评价结合贴近度法建立了桥梁承载能力评价模型来评价桥梁承载能力技术状况，采用桥梁行车道宽度与道路宽度的比值建立桥梁适应性评价模型来评价桥梁适应性，将桥梁缺损情况、桥梁承载能力情况和桥梁适应性评价进行线性加权建立桥梁技术状况综合评价模型来对桥梁技术状况进行综合评价；采用灰色系统法建立GM（1,1）模型来预测桥梁技术状况；利用遗传算法结合线性加权法建立桥梁养护费用分析模型，用最优化的原理将有限的养护资金合理的分配与利用；通过建立决策树模型、相应的典型养护措施对策库以及相应的桥梁养护项目优化、排序措施，，依据桥梁技术状况评价数据对桥梁提出相应的养护措施；编写了桥梁管理系统软件，能够方便的存储和读取桥梁的养护信息，方便养护人员对桥梁进行养护。
[Abstract]:Bridge is the throat of traffic and plays an important role in the whole transportation industry. In recent years, the bridge construction in China has made remarkable progress. However, with the development of transportation and the continuous increase of the service life of existing bridges, the problem of bridge diseases is becoming more and more serious, and many bridges have even become dangerous bridges. Therefore, the bridge maintenance and management work will become more and more important. This paper introduces the development and research situation of bridge management system and bridge management system structure at home and abroad, and establishes a bridge defect evaluation model by using AHP combined with expert consultation to evaluate the technical situation of bridge defect. Based on fuzzy comprehensive evaluation and closeness degree method, a bridge bearing capacity evaluation model is established to evaluate the technical situation of bridge bearing capacity. Using the ratio of the width of the bridge carriageway to the width of the road, a bridge adaptability evaluation model is established to evaluate the adaptability of the bridge. The comprehensive evaluation model of bridge technical condition is established by using linear weighting method to evaluate the bearing capacity and adaptability of bridge, and the GM (1 / 1) model is established by grey system method to predict the technical condition of bridge. By using genetic algorithm and linear weighting method, the bridge maintenance cost analysis model is established, and the limited maintenance funds are allocated and utilized rationally by the principle of optimization, and the decision tree model is established. According to the bridge technical condition evaluation data, the corresponding maintenance measures are put forward, and the bridge management system software is compiled, and the corresponding maintenance measures library and corresponding bridge maintenance project optimization and sequencing measures are put forward according to the bridge technical status evaluation data. Can conveniently store and read the bridge maintenance information, convenient maintenance personnel to maintain the bridge.
