| 摘 要： | 基于有限元强度折减法，运用有限元分析软件Abaqus对邢汾高速公路邢台至冀晋界段的边坡，采用不同坡率、分级开挖的施工过程和施工结束后运营期的长期稳定性进行了仿真分析，验证边坡在施工过程中的稳定性和运营期的长期稳定性，并对边坡失稳判据进行了对比验证。结果表明:两种情况的边坡都是稳定的。

| Abstract: | Based on finite element strength reduction method, this paper, in relation to the slope in the section of Xingtai-Fenyang Highway from Xingtai to Hebei-Shanxi Border, and with FEM analytical software, Abaqus, conducted simulation analysis for the excavation process in phases and its long-term stability during the operation after the construction by use of different slope ratios. Thus the stability of the slope in the construction and the permanent stability in the operation were verified and, by comparison, the failure criterion for the slope was proved. The results show that the slope is stable in both cases. |
