| 中文摘要: |
| 考虑到地震边坡破坏的机制，以京化高速公路挖方高边坡为研究背景，对地震荷载下的边坡稳定性进行了分析研究。详细分析了边坡的工程地质条件，结合实地采样试验，确定了边坡岩体的工程力学参数。利用有限元软件ABAQUS，建立了三维数值仿真模型，在试验区地震特征研究的基础上，采用拟静力法+强度折减的方法，分别模拟了地震力作用下边坡的位移变形及主应力分布规律，计算了边坡的安全系数，为边坡的加固提供了依据。 |

| Considering slope destruction mechanism under earthquake, based on excavation high slope in Jing hua highway, slope stability under earthquake is analyzed. Through analyzing engineering geology condition and combining sampling test on the spot, engineering mechanical parameters of rock slope are determined. By virtue of finite element software ABAQUS, three dimensional numerical simulation model is established. Based on earthquake character of examination region, adopting pseudo static method and strength reduction method, displacement and principal stress distribution of slope under the earthquake are simulated. Safety factor of slope is computed. This provides basis for slope reinforcement. |
