| 中文摘要: |
| 以宁武县某露天矿山为例,针对开采形成的高陡边坡存在安全隐患的问题,选取其中一处岩质边坡和一处土质边坡,采用赤平投影分析法对岩质边坡的稳定性进行分析评价,通过理正软件运用圆弧滑动法对土质边坡的稳定性进行分析评价。分析结果显示岩质边坡处于不稳定状态,土质边坡在天然条件下稳定,在暴雨及地震工况下为基本稳定状态。本文对不同类型的高陡边坡采用不同方法进行了稳定性分析,所得结论对后期施工设计提供了理论依据及数据支持,同时为类似工程的边坡稳定性分析提供了参考。 |
| 英文摘要: |
| Based on the open-pit mine in Ningwu County as an example, in view of the hidden safety problems of the high and steep slope formed by mining, one rock slope and one soil slope are selected, the stereographic projection analysis method is used to analyze and evaluate the stability of the rock slope, and the arc sliding method is used to analyze and evaluate the stability of the soil slope by Lizheng software. The analysis results show that the rock slope is unstable, the soil slope is stable under natural conditions, and is basically stable under rainstorm and earthquake conditions. In this paper, different methods are used to analyze the stability of different types of high and steep slopes. The conclusions provide theoretical basis and data support for later construction design, and provide reference for slope stability analysis of similar projects. |
