摘要
为了跨越一些地形较为复杂的地段如河流、山川等需要采用搭建桥梁的方式,而由于桥梁的刚度与路基的有一定差异,导致在二者的连接部分会出现一定沉降的现象,从而使铁路的平稳,若不进行妥善处理会对高铁的运行造成不利影响。针对此问题,从高铁铁路路基与桥梁过渡段存在的问题及问题原因入手,总结分析了过渡段施工的重要性,并结合工程实际提出了几条提高过渡段施工质量的建议,为后续高铁铁路路基与桥梁过渡段施工工程提供了一定的理论依据。
Because of the high operation speed of high-speed rail and high requirements for its stability,it has high requirements for the quality of high-speed railway.In order to cross some of the more complex terrains such as rivers,mountains,etc.,it is necessary to adopt a bridge construction method.Due to the difference between the stiffness of the bridge and the subgrade,a certain settlement will occur in the connecting part of the two,thus making the railway stable,if not properly handled,it will adversely affect the operation of the high-speed rail.Aiming at this problem starting from the problems and problems of the high-speed railway subgrade and bridge transition section,the paper summarizes and analyzes the importance of the transition section construction,and puts forward several suggestions to improve the construction quality of the transition section in combination with the actual project,which is the follow-up high-speed railway.The roadbed and bridge transition section construction project provides a certain theoretical basis.
