摘要
新建连(云港)盐(城)铁路位于沿海地区冲积平原,区域土质主要为高含水率C类黏性土,该类土作为路基改良土原土料改良施工难度极大。通过对场拌法和集中路拌法施工工艺、优缺点及控制要点的对比分析,论证了对于高含水率C类黏性土填筑路基改良施工,采用集中路拌法更为适合。该方法有效应用于连盐、徐盐等铁路建设。
The Lianyungang-Yancheng railway is located at the alluvial plain of the coastal area.The soil in this area is mainly high water content C-type cohesive soil.The construction using this type of soil as subgrade filling is very difficult.Through comparing the construction process,advantages and disadvantages,and construction control points of field mix method and centralized road mix method,it can be concluded that the concentrated road mix method is more suitable for filling subgrade using high water content C-type cohesive soil.The concentrated road mix method is effectively applied in construction of Lianyungang-Yancheng and Xuzhou-Yancheng railway.
