摘要
为进一步提高矿山高边坡稳定性,文章以实际工程为例,深入分析基于岩土工程勘察成果的矿山高边坡稳定性分析关键技术,通过工程地质勘查,采用质量指标(basic quality,BQ)、边坡质量分级(slope mass rating,SMR)和简化毕肖普法,对研究区内重点边坡的稳定性进行分析。结果显示,研究区内重点边坡安全储备不足,不利于后续矿产资源开发工作的开展。基于此,文章提出采用主动柔性防护系统与预应力锚杆相结合的综合性边坡防护手段,对高边坡稳定性分析和加固工作的开展具有重要的现实意义。
In order to further improve the stability of mine high slope,this paper takes the actual engineering as an example to deeply analyze the key technologies for mine high slope stability analysis based on geotechnical engineering survey results.Through engineering geological survey,the stability of key slopes in the study area is analyzed by using Basic Quality(BQ),Slope Mass Rating(SMR)and simplified Bishop method.The results show that the safety reserve of key slopes in the study area is insufficient,which is not conducive to the subsequent mineral resources development.Based on this,this paper proposes to use a comprehensive slope protection method combining active flexible protection system with prestressed bolt,which has important practical significance for the stability analysis and reinforcement of high slope.
