郑徐客运专线位于黄淮冲积平原,沿线第四系地层覆盖呈厚层或巨厚层状,表层更是分布有厚度巨大的软土和松软土层,需采取合理的地基加固措施,以保证路基工程工后沉降达到控制标准。根据沿线工程地质条件、线路等级及控制标准、路基部位及填高等因素,确定了郑徐客运专线路基工程采用的地基处理类型及选取原则,并以兰考南站为实例进行了详细分析,可为工程建设过程提供参考和借鉴。
The Zheng-Xu Passenger Dedicated Line is located in the Huanghuai alluvial plain. The Quaternary strata along the line are thick or thickly stratified. The surface is covered with soft soil and soft soil with huge thickness. The ground reinforcement measures should be taken to ensure Subgrade settlement after the project reached the control standards. According to the engineering geological conditions along the line, the line grade and control standard, the subgrade position and fill height and other factors, the foundation treatment type and principle of subgrade selection of Zheng-Xu Passenger Dedicated Line are determined and analyzed in detail with Lankao South Station as an example Project construction process to provide reference and reference.
