试析高速铁路路基与桥梁过渡段施工技术

Analysis on Construction Technology of Transition Section between High-speedRailway Subgrade and Bridge

近年来,我国的高速铁路事业发展迅猛,高速铁路路网日渐完善,给人们的出行提供了更多的选择。但高速铁路工程项目的线路跨度大,常常需跨越一些地形比较复杂的地区,在这种跨越工程中,往往就涉及了桥梁建设,对此类项目而言,因为高铁路基与桥梁路基的刚度差异,使得过渡段常常伴随着各种质量问题。基于此,本文重点分析了高速铁路路基与桥梁过渡段的施工技术,对高铁桥梁过渡段施工有着一定的技术指导价值。

In recent years,China's high-speed railway business has developed rapidly,and the high-speed railway network has become more and more perfect,providing people with more choices for travel.However,the high-speed railway project has a large line span and often needs to cross some areas with more complicated terrain.In this type of crossing project,bridge construction is often involved.For this type of project,because of the difference in rigidity between the high railway foundation and the bridge subgrade,the transition section is often accompanied by various quality problems.Based on this,this article focuses on the analysis of the construction technology of the transition section of the high-speed railway subgrade and the bridge,which has certain technical guidance value for the construction of the transition section of the high-speed railway bridge.
