【摘要】:橋梁建成以后,隨著時(shí)間的推移、氣候環(huán)境的變化,橋梁的性能退化速度越來(lái)越快,需要對(duì)橋梁不斷地進(jìn)行質(zhì)量監(jiān)控,從而保證在役橋梁更加經(jīng)濟(jì)節(jié)約地發(fā)揮其在道路運(yùn)輸行業(yè)中的價(jià)值。為了能夠在橋梁建成以后對(duì)其進(jìn)行及時(shí)有效的檢測(cè)、合理地對(duì)橋梁的技術(shù)狀況評(píng)估、提前預(yù)測(cè)橋梁技術(shù)狀況、節(jié)約橋梁鞏固和維修的成本、導(dǎo)出所需數(shù)據(jù)、制定合理的養(yǎng)護(hù)方案、有效地對(duì)橋梁進(jìn)行管控,本論文研究并開(kāi)發(fā)了一套科學(xué)規(guī)范的橋梁評(píng)定系統(tǒng)。該系統(tǒng)改善了目前大部分橋梁評(píng)定系統(tǒng)的算法通用性小、系統(tǒng)數(shù)據(jù)導(dǎo)出操作復(fù)雜、橋梁經(jīng)常性檢查數(shù)據(jù)錄入繁瑣等不足。論文首先比較了三種橋梁評(píng)定方法并選取最適合本課題數(shù)據(jù)的評(píng)定方法,根據(jù)實(shí)際情況對(duì)選定方法做了一定的補(bǔ)充改進(jìn);其次研究并使用實(shí)際數(shù)據(jù)對(duì)比了灰色系統(tǒng)和回歸分析的預(yù)測(cè)模型,找出了結(jié)果最精確的橋梁預(yù)測(cè)模型;最后基于橋梁參數(shù)數(shù)據(jù)庫(kù)對(duì)系統(tǒng)進(jìn)行了功能需求分析,得出系統(tǒng)的功能主要包括對(duì)橋梁的基本信息管理、橋梁部件管理、橋梁病害管理、橋梁經(jīng)常性檢查、用戶管理、權(quán)限組管理、導(dǎo)出橋梁的評(píng)價(jià)結(jié)果、病害信息、打印橋梁卡片、以及橋梁評(píng)定和預(yù)測(cè)功能等。經(jīng)過(guò)綜合比較,系統(tǒng)使用輕量級(jí)的Tomcat7服務(wù)器來(lái)減輕硬件的負(fù)載,選取Myeclipse為編程開(kāi)發(fā)工具,采用基于web技術(shù)和SSH框架的B/S模式來(lái)實(shí)現(xiàn)本系統(tǒng);并且利用FineReport報(bào)表設(shè)計(jì)器與數(shù)據(jù)庫(kù)視圖相結(jié)合開(kāi)發(fā)本系統(tǒng)的報(bào)表功能。在實(shí)驗(yàn)環(huán)境下設(shè)計(jì)多個(gè)測(cè)試用例對(duì)系統(tǒng)的功能進(jìn)行了白盒測(cè)試和黑盒測(cè)試,并完成了對(duì)系統(tǒng)性能的測(cè)試。測(cè)試結(jié)果表明系統(tǒng)在橋梁管理、橋梁評(píng)定方面功能完善,操作簡(jiǎn)便,與服務(wù)器通信穩(wěn)定,能夠完成橋梁的評(píng)定、打印評(píng)定結(jié)果,能夠較為準(zhǔn)確地預(yù)測(cè)未來(lái)技術(shù)狀況走向,系統(tǒng)響應(yīng)時(shí)間滿足用戶需求,具有較高的參考和使用價(jià)值。
[Abstract]:After the bridge is built, with the passage of time and the change of climate environment, the performance of the bridge degrades more and more quickly, so it is necessary to monitor the quality of the bridge continuously. In order to ensure that existing bridges more economically and economically play its value in the road transport industry. In order to be able to carry out timely and effective inspection after the bridge is completed, to evaluate the technical condition of the bridge reasonably, to predict the technical condition of the bridge in advance, to save the cost of bridge consolidation and maintenance, and to derive the necessary data, This paper studies and develops a set of scientific and normative bridge evaluation system. The system improves the common use of most bridge assessment systems, the complexity of system data export and the tedious input of bridge inspection data. Firstly, the paper compares three methods of bridge evaluation and selects the most suitable evaluation method for the data of this subject, and makes some supplementary improvements according to the actual situation. Secondly, the prediction model of grey system and regression analysis is compared with the actual data, and the most accurate bridge prediction model is found. Finally, the function requirement of the system is analyzed based on the bridge parameter database. The main functions of the system include the basic information management of the bridge, the management of bridge components, the management of bridge diseases, the regular inspection of bridges, the management of users, the management of authority groups, the derivation of the evaluation results of bridges, the information of diseases, the printing of bridge cards. And bridge evaluation and prediction function. After comprehensive comparison, the system uses lightweight Tomcat7 server to lighten the hardware load, selects Myeclipse as the programming development tool, and uses the B / S model based on web technology and SSH framework to realize the system. The report function of this system is developed by using FineReport report designer and database view. In this paper, several test cases are designed to test the function of the system in white box and black box, and the performance of the system is tested. The test results show that the system has perfect functions in bridge management, bridge evaluation, simple operation, stable communication with server, can complete bridge evaluation, print evaluation results, and can accurately predict the future technical situation. The response time of the system meets the needs of users and has high reference and use value.
