| 摘 要： | 结合山区高速公路建设的实践，采用大型室内模型试验，找出了荷载作用下斜坡地基上高填方路堤滑动破坏面出现的位置及形态，并确定了其极限承载力的大小。在通用条分法的理论基础上运用Visual Basic编程语言编制了斜坡地基上填方路堤极限承载力计算程序，并应用于该试验模型的计算分析，计算与试验结果的对比分析表明，利用极限平衡通用条分法不仅简单可行，且具有较高的计算精度。

| Abstract: | According to the practical experiences in the expressway construction in the mountain region, the form and position of the slip curve surface, and the ultimate bearing capacity are found out by the large scale model experiment. Based on the generalized limit equilibrium method, the computation procedure for the stability analysis of embankments on the mountain slope is programmed by using Visual Basic. The model experiment is calculated by this program; and the calculation results are compared with those from the experiment; and the comparison shows that the generalized limit equilibrium method is feasible, simple and accurate. |
