【摘要】：近些年來,隨著交通建設(shè)快速發(fā)展以及科學(xué)技術(shù)在工程中的廣泛應(yīng)用,大跨度連續(xù)梁橋在鐵路橋梁建設(shè)中占據(jù)著極其重要的地位。大家普遍認(rèn)為橋梁施工監(jiān)控環(huán)節(jié)在大跨度連續(xù)梁橋施工過程中非常重要,為了能夠保證連續(xù)梁橋在施工過程中受力狀況按理想狀態(tài)變形,橋梁能夠順利合攏,橋梁的線性能夠平順,必須保證在施工過程中做好橋梁施工監(jiān)控方面的工作,而懸臂施工過程中高程以及線形監(jiān)控就成為施工監(jiān)控中的重要的環(huán)節(jié)之一。本文以向莆鐵路京山大橋(40+64+40)m,根據(jù)連續(xù)梁橋懸臂施工的特點(diǎn),進(jìn)行了施工過程的線性監(jiān)控研究。結(jié)合施工監(jiān)控的理論計(jì)算方法,使用Midas/Civil軟件進(jìn)行仿真計(jì)算,校核該橋梁各個施工階段的監(jiān)控點(diǎn)標(biāo)高,最后實(shí)現(xiàn)了橋梁精確合攏,為相關(guān)的橋梁施工過程提供了依據(jù)。
[Abstract]:In recent years, with the rapid development of traffic construction and the wide application of science and technology in engineering, long-span continuous beam bridge plays an extremely important role in the construction of railway bridges. It is generally believed that the monitoring link of bridge construction is very important in the construction process of long-span continuous beam bridge. In order to ensure that the stress condition of continuous beam bridge is deformed according to the ideal state during the construction process, the bridge can close smoothly. The linearity of the bridge can be smooth, it is necessary to ensure that the bridge construction monitoring work in the construction process, and the cantilever construction process of elevation and linear monitoring has become one of the most important links in the construction monitoring. According to the characteristics of cantilever construction of continuous beam bridge, a linear monitoring study on the construction process of Jingshan Bridge on Xiangpu Railway is carried out in this paper. Combined with the theoretical calculation method of construction monitoring and control, the simulation calculation is carried out by using Midas/Civil software to check the elevation of the monitoring points in each construction stage of the bridge. Finally, the accurate closure of the bridge is realized, which provides the basis for the relevant bridge construction process.
