摘要
在社会经济的发展和城镇化建设规模的扩大中,城市道路和高速铁路也得到很大的发展,对相关的建设工作也产生了很大的影响。在我国的高速铁路当中,桥梁是主要的承载结构,在其中肩负着极为重要的作用,因此在今后的交通线路发展当中,道路下穿既有高铁桥梁工程已经成为重要的工程方式。高速铁路的列车运营速度都比较快,而且高速铁路运输除了在特殊的情况下都是不能被中断的,因此对于运营中的高铁桥梁基础变位控制的要求就会比较高。本文主要是对下穿道路的施工和运营可能产生的影响进行一定的分析,在这样的背景下,道路下穿段运营对既有的高铁桥梁基础影响进行了探究。
In the development of social economy and the expansion of urbanization construction scale,urban roads and high-speed railway have also been greatly developed,which also has a great impact on the related construction work.In China's high-speed railway,bridges are the main bearing structures,which shoulder a very important role.Therefore,in the future development of traffic lines,it has become an important engineering way to cross the existing high-speed railway bridge project under the road.The train operation speed of high-speed railway is relatively fast,and the high-speed railway transportation can not be interrupted except in special circumstances,so the requirements for the displacement control of the highspeed railway bridge foundation in operation will be relatively high.However,the operation of Underpass section will have a certain impact on the existing high-speed railway bridges,so this paper mainly focuses on the construction and operation of Underpass section。
