The actuality and problems of bridge management system 橋梁管理系統(tǒng)應用現(xiàn)狀與問題
Bridge management system 橋梁管理系統(tǒng)
Bridge technique condition evaluation and prediction are the two aspects among the bridge management system . the research work has established the theoretical foundation for developing comprehensive bridge management system suited to chinese bridge management sectors 橋梁技術(shù)狀況評價與預測僅是橋梁管理系統(tǒng)的二個方面,本文的研究為建立完整、科學且適合我國國情的橋梁管理系統(tǒng)奠定了理論基礎(chǔ),也為橋梁管理系統(tǒng)的研究、開發(fā)提供了有益的經(jīng)驗。
Considered the present condition of liaoning province , the evaluation and prediction method of liaoning province bridge technique condition is analyzed , then bridge condition changed - contingency evaluated method is introduced , negative index curve is chosen as the regression analysis model of the bridge condition prediction , and based on the information of bridge management system in the liaoning highway , the parameters of model are calibrated , the average repaired life of bridge is also calculated , the definite method of the bridge ' s repaired year is given , at the same time the markov chain model of bridge condition prediction is presented 結(jié)合遼寧省的橋梁工程及管理具體情況,研究了遼寧省橋梁技術(shù)狀況評價與預測方法,引入橋梁缺損狀況變權(quán)評定方法,選擇負指數(shù)曲線作為橋梁缺損狀況預測的回歸分析模型,并依據(jù)遼寧省干線公路橋梁管理系統(tǒng)中的橋梁狀況信息,標定了模型的參數(shù),計算橋梁中修及大修(或改建)的平均年限,給出橋梁大中修年份的確定方法,同時也建立了橋梁缺損狀況預測的馬爾可夫鏈概率模型。
