高速铁路桥梁相比原铁路桥梁具有更强大的动力效应,所以其强度和刚度等方面要相比更优越才能满足铁路高平顺等方面的要求,这导致高速铁路梁体自重相比更大,将900t箱梁应用于高速铁路工程施工过程中,不仅可以提升高铁建设的效率,减缓高速列车所产生的冲击破坏力,使桥梁的使用寿命延长,而且对提升其整体性能也具有重要的作用,所以高速铁路900t箱梁架设受到社会各界的高度重视。本文为提升我国高速铁路900t箱梁架设的水平,对其关键技术展开研究。
Compared with the original railway bridge, the high-speed railway bridge has a stronger dynamic effect, so its strength and stiffness are superior to meet the requirements of the high-speed railway, which leads to the fact that the weight of the high- 900t box girder used in high-speed railway construction process, not only can improve the efficiency of high-speed rail construction, slow down the impact of high-speed train destructive power to extend the life of the bridge, but also to enhance its overall performance also plays an important role, so High-speed railway 900t box girder erection by the community attach great importance. In order to improve the erection level of 900t box girder in China’s high-speed railway, this paper studies its key technologies.
