摘　　要：新建蒙华铁路24合同段地处长江中下游江汉平原,铁路路基C组填料来源不广泛,结合施工区域粉砂夹粉质黏土以及细砂较丰富的情况,提出了黏土包砂填料替代传统C组填料施工的方法。论文详细介绍了重载铁路黏土包砂路基填筑关键工艺,可为类似工程施工提供一定的借鉴和指导。The 24 contract section of the newly built Menghua railway is located in Jianghan Plain in the middle and lower reaches of the Yangtze River, and the source of group C filling materials for railway subgrade is not extensive. Combined with the rich situation of silty sand mixed with silty clay and fine sand in the construction area, the construction method of replacing the traditional group C filling materials with clay packed with sand is proposed. This paper introduces in detail the key technology of clay sand subgrade filling for heavy haul railway, which can provide some reference and guidance for similar engineering construction.
