    NUMERICAL SIMULATION OF THE HIGH ROCK SLOPE STABILITY UNDER THE COMPLEX FORCE CONDITIONS

    • 摘要: 本文使用基于有限差分法的FLAC软件对岩质高边坡进行了数值模拟分析。在着重考虑桥基荷载影响的思路下,通过模拟高速公路边坡开挖前、开挖后、桥基施工后以及施加锚杆等加固措施后这4种不同复杂工程情况下的计算模型,得出以上4种模型的边坡位移场、塑性区分布和边坡稳定性系数的变化,以此来评价岩质高边坡的稳定性。本文重点地研究了桥基荷载对于边坡稳定性的影响以及锚索加固对于补偿桥基荷载负面作用的大小。

       

      Abstract: In this paper, by using the FLAC procedure which is based on the finite difference method, we make a numerical simulation of high rock slope. Through the simulation of the four complex engineering conditions that contains before the slope excavation, after the slope excavation, under the bridge foundation load and under the anchor reinforcement, also considering the bridge foundation load's impact on the slope, We can get the slope displacement's change, the distribution of the slope plastic zone's changes and the change in slope stability factor, and then we can evaluate high rock slope stability. This paper focuses on the bridge foundation load's impact on the slope stability and the compensation impact of the cable reinforcement to the bridge foundation load’s negative effect on the slope stability.
