摘　　要：本文对某高速公路软土路基沉降的原因进行了分析,对软土路基沉降规律与公式进行了观测与计算。通过计算后得出深厚软基工沉降占总沉降约7%,范围值为5%,沉降系数为0.1。且路基最终沉降S和软土厚度的关系为:S=(0.08~0.13)H-0.0211。进而得出和归纳出软土路基沉降变形的规律,为后期软土地基沉降控制提出了措施与参考。This article analyzes the reasons for the settlement of a soft soil roadbed on a certain expressway,observes and calculates the settlement laws and formulas of the soft soil roadbed.Through calculation,it is concluded that the settlement of deep soft foundation accounts for about 7%of the total settlement,the range value is 5%,and the sedimentation coefficient is 0.1.And the relationship between the final settlement S of the roadbed and the thickness of the soft soil is:S=(0.08~0.13)H-0.0211.Furthermore,the laws of settlement and deformation of soft soil roadbed are derived and summarized,providing references for controlling settlement of soft soil roadbed in the later stage.
