| 摘 要： | 论述了广元北段某边坡的地形地貌、地质特征和边坡破坏的成因机制，通过极限平衡法和2维／3维有限元法的稳定性定量计算与分析可知，该边坡处于极限平衡状态，饱水情况下易出现大面积滑动，针对边坡的特征和工程实际情况，对边坡处治方案进行比较分析，提出了边坡的合理整治措施。

| Abstract: | Based on the terrain physiognomy and geographical characteristic in the north area of Guangyuan, mechanism of the slope destruction is discussed. According to stability calculation analysis of the slope by means of limit equation method and FEM, the slope is on the limit equilibrium state and easy to slide under the condition of water saturation. The appropriate engineering treatments are also proposed through contrasting analysis. |
