| 摘 要： | 高速公路施工中应掌握软弱路基在路堤填筑过程中的沉降规律,通过应用邓肯—张模型和比奥固结有限元程序对软土路基条件下的沉降进行有限元模拟,揭示了沉降过程中软土的固结规律,得到了比较接近实测值的计算结果,对于指导路基施工具有一定的意义。

| Abstract: | It is a main concern about the settlement laws of the soft roadbed during the construction of a road foundation. In this paper, the settlement of a soft soil roadbed is simulated by means of the Duncan-Chang model and Biot's consolidation finite element program. Consolidation laws of a soft soil foundation have been revealed and the calculated values are found close to the results observed, which will be of importance in guiding the construction of roadbeds. |
