| 中文摘要: |
| 降雨是边坡失稳的主要诱发因素之一，是探讨边坡稳定性必须要考虑的条件，为了探究降雨对岩质边坡稳定性的影响，我们以海螺旗下某矿山原始边坡为研究对象，研究内容为持续96 h降雨量74.4 mm/h的情况下，岩质边坡瞬时安全系数的变化。采用的计算软件为Geostudio，使用方法为极限平衡法。根据模拟结果显示，边坡瞬时安全系数变化可以分为三个阶段，分别为上升阶段、下降阶段、稳定阶段，其后分别对三个阶段进行分析，研究安全系数变化的原因。 |

| Rainfall is one of the main inducing factors of slope instability， and it is necessary to consider the conditions of slope stability. In order to explore the influence of rainfall on the stability of rock slope， we take the original slope of a mine under Conch Banner as the research object. The research content is the change of instantaneous safety factor of rock slope under the condition of continuous rainfall of 74.4 mm/h for 96 h. The calculation software used is geostudio， using the limit equilibrium method. According to the simulation results， the change of the instantaneous safety factor of the slope can be divided into three stages， namely， the rising stage， the falling stage and the stable stage， and then the three stages are analyzed to study the reasons for the change of the safety factor. |
