摘　　要：本文就路基沉降观测资料进行深入分析,总结出路基沉降与软土层厚度及填土高度的关系和规律,并分析了原因,推导出计算路基沉降的公式,提出了判断填土速率快慢和填土高度变化大小的新方法。On the base of analysis of observed data of Settlement on embankment, the relation between the settlement of embankment and the depth of subsurface soft soil and the depth of fill is investigated, the authors also derivated a new formula for calculation of settlement of embankment, and put forward a new method to control the rate and depth of fill construction.
