| 中文摘要: |
| 研究对象为海螺名下水泥原料矿山边坡，研究内容为在降雨和地震等因素影响下边坡的稳定性。采用的方法有赤平投影法和Geostudio模拟，其中Geostudio模拟计算主要使用方法为极限平衡法，模拟计算边坡在自然状态、降雨、地震、降雨同时地震4种情况下的安全系数。根据模拟结果显示，在自然工况和连续强降雨情况下边坡都是稳定的；在地震工况下边坡稳定性较差，有可能发生失稳；在降雨同时发生地震极端情况下，边坡稳定性极差。整体的边坡稳定性较好，但在特殊工况下仍有失稳的可能性，须采取一定的加固措施，但因研究对象为未开采的水泥原料矿山边坡，边坡加固措施应根据工程设计而安排，在此文中不作展述。 |
| 英文摘要: |
| The research object is the slope of cement raw material mine under the name of conch. The research content is the stability of the slope under the influence of rainfall and earthquake. The methods used are stereographic projection method and geostudio simulation. Geostudio simulation calculation mainly uses the limit equilibrium method to simulate and calculate the safety factor of the slope under four conditions : natural state, rainfall, earthquake, rainfall and earthquake. According to the simulation results, the slope is stable under natural conditions and continuous heavy rainfall. The slope stability is poor under seismic conditions, and it is possible to lose stability. In the extreme case of rainfall and earthquake, the slope stability is very poor. The overall slope stability is good, but there is still the possibility of instability under special conditions, and certain reinforcement measures must be taken. However, because the research object is the slope of the unexploited cement raw material mine, the slope reinforcement measures should be arranged according to the engineering design, which is not described in this article. |
