摘　　要：新建的攀枝花南站地基为昔格达层,昔格达地层物理力学性质非常差,遇水易软化和崩解。因此,研究昔格达层混合填料所填筑而成的高填方路堤的工后沉降值具有非常重要的理论价值和工程意义。借助路基工程中常用的双曲线法和三点法对攀枝花南站典型断面工后沉降进行预测分析研究结果,可以为类似高填方路堤沉降研究提供参考和借鉴。The foundation of the new Panzhihua south railway station is the Xigeda strata. The physical and mechanical properties of Xigeda strata are extremely poor, which is easy to cause geological hazards. Therefore, it is of great theoretical and engineering significance to study the post-construction settlement of high-fill embankments filled with Xiageda layer mixed fillers. The results of the prediction analysis of the post-construction settlement of the typical section of the Panzhihua South Station,using the hyperbolic and three-point methods commonly used in subgrade engineering, can provide reference for similar projects.
