【摘要】：橋梁建成以后,由于受到氣候、環(huán)境因素的影響,結(jié)構(gòu)材料會被腐蝕和逐漸老化,長期的動靜載作用,其強(qiáng)度和剛度隨著時間的增加而降低。這不僅會影響行車安全,也會使橋梁的使用壽命縮短。橋梁結(jié)構(gòu)健康監(jiān)測是對橋梁結(jié)構(gòu)及其工作環(huán)境進(jìn)行實時監(jiān)測,并利用監(jiān)測數(shù)據(jù)分析大橋的健康狀況、評價大橋的承受靜動載的能力和結(jié)構(gòu)的安全可靠性,為運營養(yǎng)護(hù)提供決策依據(jù)。本文研究的項目為上海巨一科技發(fā)展有限公司為上海松江地區(qū)新建的一座跨黃浦江的大橋的結(jié)構(gòu)健康監(jiān)測系統(tǒng)的設(shè)計開發(fā)項目,同時本項目也是上海市橋梁大數(shù)據(jù)研究的課題之一,本人為該項目的項目經(jīng)理,負(fù)責(zé)該項目的設(shè)計、開發(fā)、實施以及后期運營維護(hù)工作。本文主要的工作內(nèi)容為依據(jù)據(jù)項目需求,開發(fā)一套能滿足辰塔公路跨黃浦江大橋的結(jié)構(gòu)健康監(jiān)測系統(tǒng),通過在橋梁結(jié)構(gòu)重要截面位置安裝獲能取代表橋梁環(huán)境、荷載及結(jié)構(gòu)響應(yīng)信息的傳感器設(shè)備,結(jié)合定期人工巡檢的檢測數(shù)據(jù),監(jiān)測橋梁可能存在的狀態(tài)改變,盡早發(fā)現(xiàn)結(jié)構(gòu)損傷,并對橋梁結(jié)構(gòu)的改變及損傷進(jìn)行評估,提出調(diào)整、維修或管理建議。根據(jù)相關(guān)要求我們結(jié)合以往系統(tǒng)的開發(fā)經(jīng)驗和國內(nèi)外同行的經(jīng)驗教訓(xùn),通過對橋梁的環(huán)境特點、結(jié)構(gòu)特點及軟件系統(tǒng)功能性需求進(jìn)行分析,首先進(jìn)行了系統(tǒng)的總體設(shè)計,完成了橋梁監(jiān)測點的布置及相關(guān)監(jiān)測參數(shù)的確定,傳感器、采集設(shè)備、通訊設(shè)備、存儲數(shù)據(jù)處理等設(shè)備的設(shè)計、選型、采購、安裝調(diào)試工作；在系統(tǒng)軟件上完成了對數(shù)據(jù)自動采集軟件、人工巡檢養(yǎng)護(hù)軟件、綜合預(yù)警安全評估軟件、用戶界面軟件、中心數(shù)據(jù)庫軟件幾個子系統(tǒng)分別進(jìn)行了設(shè)計、開發(fā)和調(diào)試工作。辰塔公路跨黃浦江大橋結(jié)構(gòu)健康監(jiān)測系統(tǒng)的建成運營,標(biāo)志著代表具有最新技術(shù)的第三代橋梁結(jié)構(gòu)監(jiān)測系統(tǒng)的設(shè)計開發(fā)成功并投入橋梁結(jié)構(gòu)監(jiān)測的實際運用中,具有重大的科研和應(yīng)用價值。
[Abstract]:After the bridge is completed, due to the influence of climate and environmental factors, the structural material can be corroded and gradually aged, and the long-term static and static loading function, its strength and rigidity decrease with the increase of time. This will not only affect driving safety, but also shorten the service life of the bridge. The bridge structure health monitoring is to carry out real-time monitoring on the bridge structure and its working environment, and utilize the monitoring data analysis bridge's health condition, evaluate the capacity of the bridge to withstand the static load and the safety and reliability of the structure, and provide decision basis for the operation and maintenance. The project is a design and development project of Shanghai Giant Science and Technology Development Co., Ltd. to build a new construction health monitoring system across the Huangpu River, which is a new bridge across the Huangpu River in Shanghai. At the same time, this project is also one of the subjects of the research on bridge data in Shanghai. I am the project manager of the project, who is responsible for the design, development, implementation and post-operation maintenance of the project. The main contents of this paper are to develop a structure health monitoring system which can meet the crossing of the Huangpu River Bridge in ChenTower Highway according to the project requirements, and adopt sensor equipment which can take representative of bridge environment, load and structural response information at the important section position of the bridge structure. Combined with the detection data of periodic manual inspection, monitoring the possible state change of the bridge, finding the structural damage as early as possible, and evaluating the change and damage of the bridge structure, and proposing adjustment, maintenance or management suggestions. According to the relevant requirements, we combine the development experience of the past system and the experiences and lessons of the domestic and foreign peers, and through the analysis of the environmental characteristics, structural characteristics and functional requirements of the software system, the overall design of the system is firstly carried out. The layout of bridge monitoring points and the determination of relevant monitoring parameters, sensors, acquisition equipment, communication equipment, storage data processing and other equipment shall be designed, selected, purchased and installed and debugged; the software for automatic data acquisition and manual inspection and maintenance shall be completed on the system software. The design, development and debugging of integrated early warning safety assessment software, user interface software and central database software are respectively carried out. The completion and operation of the health monitoring system across the Huangpu River Bridge in ChenTower Highway indicates that the design and development of the third generation bridge structure monitoring system with the latest technology is successful and put into the practical application of bridge structure monitoring, and has great scientific research and application value.
