浅谈铁路既有线帮填路基施工

Discussion on Subgrade Filling Construction of Existing Line in Railways

大力规划发展铁路建设是资源的需求导向,新建高铁、货运专线、既有线改造等项目接连不断,既有线改造路基帮填施工更是频繁出现,这就要求我们有扎实的施工技术及完善的安全管理体制,既有铁路边坡挖台阶、帮填路基压实质量、边坡防护、排水系统的设置都要落到实处。论文对既有线路基帮填施工工艺及其安全管理展开分析,供读者参考。

Vigorously planning and developing railway construction is the demand-oriented of resources, new high-speed railway, freight dedicated line, existing line transformation and other projects are continuous, existing line transformation roadbed filling construction is more frequent. This requires us to have solid construction technology and perfect safety management system, the existing railway slope excavation steps, fill subgrade compaction quality, slope protection, drainage system settings should be implemented. This paper analyzes the construction technology and safety management of subgrade filling of existing line, for readers' reference.
