层状岩质边坡稳定性赤平投影法分析及防治措施

Analysis and Preventive Measures of Stereographic Projection of Stratified Rock Slope

摘要: 以广德县新都露天矿为实例，基于赤平投影的方法对边坡进行稳定性分析，解决实际工程项目边坡定性稳定分析的问题并提出防护措施建议。文中利用赤平投影的原理，通过理正软件绘画出赤平投影图进行边坡稳定性分析。得出III区边坡层面和优势结构面1的组合有发生楔体滑动失稳的可能性，采场其余各区边坡主要结构面组成的楔体发生滑动的可能性小，并根据岩体结构特征分析其破坏模式可为圆弧形破坏，提出了排水、锚固、边坡检测等后期的防护措施。

Abstract: Taking Guangde County Xindu opencast mine as an example, stability analysis of slope based on red flat projection method has been made, and feasible protective measures according to the actual engineering slope have been put forward to solve the problem of qualitative analysis of slope stability engineering project. In this paper, based on the principle of stereographic projection, the slope stability was analyzed by Lizheng software drawing stereographic projection. It is concluded that the III slope level and the combination of 1 dominant discontinuities has the possibility of occurrence of wedge sliding instability, the possibility of wedge structure mainly through the remaining districts consisting of sliding surface of slope is small. According to the structural characteristics of rock mass, the failure mode can be broken by arc failure. Some protection measures such as drainage, anchorage and side slope detection are put forward.
