摘要
在公路桥梁施工中,经常会穿越崇山峻岭、江河湖泊,如果遇到既有铁路则会涉及到与既有铁路的交叉问题,有时需采用上跨形式通过既有铁路,此时既要保证公路桥梁的质量,又要注重施工过程中的安全,尤其要避免施工影响既有铁路行车安全,所以涉及到的施工技术难度较大,为了更好地促进我国公路桥梁建设事业的发展,需要深入研究上跨既有铁路时公路桥梁施工技术,保证施工安全和施工质量。基于此,结合省内相关公路跨铁路施工案例,简要探讨了上跨既有铁路时公路桥梁施工技术。
In the construction of highway bridges,it often crosses mountains,rivers and lakes.If there is an existing railway,it will involve the problem of crossing with the existing railway.Sometimes it is necessary to cross the existing railway in the form of up crossing.At this time,it is necessary to not only ensure the quality of highway bridges,but also pay attention to the safety in the construction process,especially to avoid the construction affecting the running safety of the existing railway,so it involves the construction technology is difficult.In order to better promote the development of highway bridge construction in China,it is necessary to study the construction technology of highway bridge when crossing the existing railway to ensure the construction safety and construction quality.Based on this,this paper discusses the construction technology of highway bridge when crossing the existing railway.
