【摘要】：“十一五”規(guī)劃以來,我國高速鐵路進(jìn)入黃金發(fā)展期,高速鐵路網(wǎng)不斷擴(kuò)容,越來越多的高鐵、城際鐵路興建,帶動(dòng)大跨度橋梁進(jìn)入繁榮發(fā)展階段。為保證橋梁結(jié)構(gòu)運(yùn)營的安全性、可靠性、耐久性、行車舒適性等,對特大橋梁施工全過程進(jìn)行監(jiān)測監(jiān)控,已成為大型橋梁建設(shè)必不可少的重要環(huán)節(jié)。懫用懸臂澆筑法施工的預(yù)應(yīng)力連續(xù)梁橋,在施工過程中必然會(huì)引起復(fù)雜的內(nèi)力和位移變化,為了確保大橋的施工質(zhì)量和安全,必須進(jìn)行橋梁施工監(jiān)控。以黃家村鐵路橋?yàn)楣こ瘫尘?懫用自適應(yīng)的施工控制方法,對黃家村鐵路橋施工監(jiān)控進(jìn)行研究,主要進(jìn)行了如下工作:1、根據(jù)黃家村鐵路橋設(shè)計(jì)及結(jié)構(gòu)特點(diǎn),按照橋梁施工及監(jiān)控要求,編制了該橋的施工階段監(jiān)控方案。2、利用Midas/Civil建立黃家村鐵路橋的計(jì)算機(jī)三維仿真模型,進(jìn)行鐵路橋施工階段的仿真模擬,分析了橋梁在施工階段及大橋合攏后的箱梁受力和線形變化情況。并用了參數(shù)敏感性分析法,對影響橋梁結(jié)構(gòu)受力和線形的設(shè)計(jì)參數(shù)進(jìn)行分析,以便獲得關(guān)鍵設(shè)計(jì)參數(shù)對主梁線形和應(yīng)力影響的規(guī)律。3、依據(jù)監(jiān)控方案對黃家村鐵路橋主橋進(jìn)行了橋梁結(jié)構(gòu)線形監(jiān)控。主要監(jiān)控了橋梁關(guān)鍵斷面的溫度及應(yīng)力變化情況,各節(jié)段的標(biāo)高和全橋的線形。根據(jù)橋梁現(xiàn)場監(jiān)測結(jié)果對理論計(jì)算參數(shù)進(jìn)行修正,使理論計(jì)算參數(shù)和現(xiàn)場實(shí)際情況相吻合,從而指導(dǎo)橋梁現(xiàn)場施工,確保了橋梁整個(gè)施工過程的質(zhì)量和安全。4、分析主梁應(yīng)力及線形監(jiān)測數(shù)據(jù),通過實(shí)測值與理論值對比可知:黃家村鐵路橋主橋理論線形計(jì)算結(jié)果和實(shí)測線形結(jié)果基本吻合,黃家村鐵路橋主橋順利合龍,線形平順,各項(xiàng)指標(biāo)滿足規(guī)范要求;黃家村鐵路橋主橋施工過程中各控制截面的實(shí)測應(yīng)力結(jié)果和理論應(yīng)力計(jì)算結(jié)果基本吻合,橋梁施工過程中結(jié)構(gòu)始終處于安全狀態(tài)。
[Abstract]:Since the 11th Five-Year Plan, China's high-speed railway has entered the golden period of development, the high-speed railway network has been continuously expanded, more and more high-speed rail, inter-city railway construction, driving long-span bridges into the stage of prosperity and development. In order to ensure the safety, reliability, durability and driving comfort of the bridge structure, monitoring and monitoring of the whole process of the construction of the large bridge has become an indispensable and important link in the construction of the large bridge. In order to ensure the construction quality and safety of the bridge, the prestressed continuous beam bridge constructed by cantilever pouring method will inevitably cause complex internal force and displacement changes during the construction process. In order to ensure the construction quality and safety of the bridge, it is necessary to carry out the bridge construction monitoring and control. Taking the Huangjia village railway bridge as the engineering background and using the adaptive construction control method, the construction monitoring and control of the Huangjiacun railway bridge is studied. The main work is as follows: 1. According to the design and structure characteristics of the Huangjiacun railway bridge, According to the requirements of bridge construction and monitoring, the monitoring scheme of the bridge in construction phase. 2. The computer 3D simulation model of Huangjiacun railway bridge is established by Midas / Civil, and the simulation of the construction stage of the bridge is carried out. The stress and linear changes of the bridge box girder during the construction stage and after the bridge closure are analyzed. The parameter sensitivity analysis method is used to analyze the design parameters which affect the force and the line shape of the bridge structure. In order to obtain the influence of key design parameters on the shape and stress of the main beam, the main bridge of Huangjiacun railway bridge was monitored according to the monitoring scheme. The temperature and stress of the key section of the bridge, the elevation of each section and the alignment of the whole bridge are monitored. According to the monitoring results of the bridge, the theoretical calculation parameters are modified to make the theoretical calculation parameters coincide with the actual situation on the spot, thus guiding the bridge construction on the spot. The quality and safety of the whole construction process of the bridge are ensured. The stress and linear monitoring data of the main girder are analyzed. By comparing the measured values with the theoretical values, it can be seen that the calculated results of the theoretical alignment of the main bridge of Huangjiacun Railway Bridge are basically consistent with the measured results. The main bridge of Huangjiacun railway bridge is closed smoothly, the alignment is smooth, the indexes meet the requirements of the code, the measured stress results of each control section in the construction process of the main bridge of Huangjiacun railway bridge are basically consistent with the theoretical stress calculation results. The structure of the bridge is always in a safe state during the process of construction.
