摘要:
旧路拓宽工程往往会涉及到新老路基结合问题.结合合肥铁路枢纽改造工程,利用离心模型试验研究路基高度、拼接台阶断面尺寸、新路基边坡率等因素对新老路线的列车安全运营和路基稳定性的影响,提出适合膨胀土地区的新老路基拼接技术包括设计方法、施工工艺、控制标准等.将对类似的改扩建工程提供理论支持和示范借鉴,对铁路的改扩建工程建设具有较大的指导意义和应用价值.
Abstract:
Old road widening projects often involve the problem of combining new and old roadbed. Combined with the Hefei railway hub renovation project, the influence of subgrade height, splicing step section size, new subgrade slope rate and other factors on the safe operation and subgrade stability of new and old routes was studied by centrifugal model experiment, and the new and old subgrade splicing technologies suitable for expanding land areas were proposed, including design methods, construction processes, control standards, etc. It will provide theoretical support and demonstration reference for similar reconstruction and expansion projects, which has great guiding significance and application value for the construction of railway reconstruction and expansion projects.
