【摘要】：橋梁是交通的咽喉，在整個(gè)交通運(yùn)輸行業(yè)有著舉足輕重的作用。近年來，我國橋梁工程建設(shè)取得了舉世矚目的進(jìn)步，然而隨著交通事業(yè)的發(fā)展和在役橋梁使用年限的不斷增加，橋梁的病害問題也日益嚴(yán)重，很多橋梁甚至已經(jīng)成為危橋，因此橋梁養(yǎng)護(hù)管理工作也就變的益發(fā)重要。 本文介紹了國內(nèi)外橋梁管理系統(tǒng)和橋梁管理系統(tǒng)結(jié)構(gòu)的發(fā)展和研究情況；利用AHP結(jié)合專家咨詢的方法建立了橋梁缺損情況評(píng)價(jià)模型來評(píng)價(jià)橋梁缺損技術(shù)狀況，利用模糊綜合評(píng)價(jià)結(jié)合貼近度法建立了橋梁承載能力評(píng)價(jià)模型來評(píng)價(jià)橋梁承載能力技術(shù)狀況，采用橋梁行車道寬度與道路寬度的比值建立橋梁適應(yīng)性評(píng)價(jià)模型來評(píng)價(jià)橋梁適應(yīng)性，將橋梁缺損情況、橋梁承載能力情況和橋梁適應(yīng)性評(píng)價(jià)進(jìn)行線性加權(quán)建立橋梁技術(shù)狀況綜合評(píng)價(jià)模型來對(duì)橋梁技術(shù)狀況進(jìn)行綜合評(píng)價(jià)；采用灰色系統(tǒng)法建立GM（1,1）模型來預(yù)測(cè)橋梁技術(shù)狀況；利用遺傳算法結(jié)合線性加權(quán)法建立橋梁養(yǎng)護(hù)費(fèi)用分析模型，用最優(yōu)化的原理將有限的養(yǎng)護(hù)資金合理的分配與利用；通過建立決策樹模型、相應(yīng)的典型養(yǎng)護(hù)措施對(duì)策庫以及相應(yīng)的橋梁養(yǎng)護(hù)項(xiàng)目?jī)?yōu)化、排序措施，，依據(jù)橋梁技術(shù)狀況評(píng)價(jià)數(shù)據(jù)對(duì)橋梁提出相應(yīng)的養(yǎng)護(hù)措施；編寫了橋梁管理系統(tǒng)軟件，能夠方便的存儲(chǔ)和讀取橋梁的養(yǎng)護(hù)信息，方便養(yǎng)護(hù)人員對(duì)橋梁進(jìn)行養(yǎng)護(hù)。
[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.
