摘　　要：根据高速公路高液限土路堤的变形特性,建立了路堤变形的数学力学模型,该模型综合考虑了地基的弹塑性以及路面和地基的协同变形。编制了适用于高液限土路堤的有限元计算程序,并用该程序计算了某路堤的变形。计算的路堤水平位移和垂直沉降与实测值一致,说明高液限土路堤变形的有限元计算结果可用于动态的指导施工。According to the deformation characteristic of the high liquid limit soil embankment of the expressway, a numerical mechanics model for analyzing the deformation of embankment was established, in which the elastoplasticity of foundation and the cooperation deformation of road surface and roadbed were comprehensively taken into account, then the finite element calculation program was made out for analyzing the deformation of high liquid limit soil embankment. The deformation of some embankment was calculated by use of this program, and the calculated horizontal displacement and vertical depression of the embankment were equivalent to the measured ones. It indicates that the results calculated by finite element method can used to dynamically guide the construction of high liquid limit soil embankment.
