【摘要】：随着矿业、交通运输业、水利和建筑业的快速发展,露天矿边坡、废石场、尾矿坝和公路铁路的路堑边坡等中岩质边坡工程的数量急剧增加,边坡失稳、滑塌等灾害事故时有发生,边坡稳定性问题日益受到重视和关注。因此,对边坡稳定性分析计算及工程措施研究仍然具有重要的理论和工程实际意义。本文以实际工程为例,以某岩质边坡对象,首先根据实际情况,分析了影响边坡稳定性的各种因素及工程可能存在各种情况,找出最不利工况,采用赤平投影法、Bisop法和Mogenstern-Price法对考虑和不考虑岩体节理影响的边坡稳定性分别进行了分析计算,表明这些分析方法是节理岩质边坡稳定性判别的有效方法,能够反映岩体结构对岩质边坡稳定性影响的敏感性,验证了节理对边坡稳定性的不利影响,Mogenstern-Price法还可以考虑组合滑动面的情况;在以上分析计算的基础上,提出了对不稳定边坡处理的工程治理和防护措施的不同方案,供工程设计和施工选用。论文研究结果对类似工程有一定的借鉴作用。
[Abstract]:With the rapid development of mining, transportation, water conservancy and construction, the number of rock slope projects such as open-pit slope, waste rock field, tailings dam and highway and railway cutting slope has increased sharply and the slope is unstable. Landslide and other disasters occur from time to time, and slope stability has been paid more and more attention. Therefore, the analysis and calculation of slope stability and the study of engineering measures still have important theoretical and engineering significance. In this paper, taking a rock slope as an example and taking a certain rock slope as an example, according to the actual situation, the factors affecting the stability of the slope and the possible conditions of the project are analyzed, and the most unfavorable working conditions are found out, and the method of plane projection is adopted. The Bisop method and the Mogenstern-Price method are used to analyze and calculate the slope stability considering and disregarding the influence of rock joints, respectively. The results show that these methods are effective methods for judging the stability of jointed rock slopes. It can reflect the sensitivity of rock structure to the stability of rock slope and verify the adverse effect of joints on slope stability. Mogenstern-Price method can also consider the situation of combined sliding surface. On the basis of the above analysis and calculation, different schemes of engineering treatment and protection measures for unstable slope treatment are put forward, which can be used for engineering design and construction. The results of this paper can be used for reference to similar projects.
