摘要
我国既有铁路多为普速铁路,其中路基工程的占比普遍较高,既有路基工程的现状直接影响铁路的运输能力。受修建技术、投资能力和自然环境限制,既有铁路路基常出现边坡变形、排水不畅和宽度不足等问题,路基的病害、失修问题急需得到解决。文章依托某黄土地区普速铁路的路基现状调查,研究黄土地区既有铁路路基设施的提升改造技术,通过改造处理保证铁路运输能力,对同类问题提供参考。
Most of the existing railways in China are general-speed railways,and the proportion of roadbed engineering is generally higher.The status of the existing roadbed engineering directly affects the transportation capacity of the railway.Limited by construction technology,investment capacity and natural environment,the existing railway subgrade often appears problems such as slope deformation,poor drainage and insufficient width,and the problems of roadbed disease and disrepair need to be solved urgently.Based on the investigation of roadbed status of general-speed railway in loess region,this paper studies the upgrading and renovation technology of existing railway roadbed facilities in loess region,and gives specific renovation scheme,which ensures railway transportation capacity through renovation and treatment,and provides reference for similar problems.
