| 摘 要： | 文章依托某线路工程，分析软土路基的失稳机理，探讨线路工程穿越软土区时，成层软土路基可行的极限填高计算方法。通过填高与稳定性的横向和纵向分析得出路基的极限填筑高度，再用数值法计算由填高产生的路堤和路基内位移分布。研究表明，用整体稳定性确定成层软土的极限填筑高度是可行的。

| Abstract: | Taking one railway line engineering as example, the article analyzes the instability mechanism of soft subgrade and discusses the method for calculating the maximum fill height of soft soil subgrade in the construction area.The transverse and vertical stability analysis is used to calculate the height,and the result can be used to calculate the displacement distribution that caused by road embankment and subgrade.The study result shows that using the global stability to calculate the max - imum fill height is feasible. |
