摘　　要：系统剖析了新岭露天矿边坡的地质特征,针对性地探索了预应力锚索加固作为边坡防护措施的应用潜力;基于严格的力学平衡理论框架,并兼顾经济效益的考量,调整了边坡预应力锚索加固的设计参数,实现了结构稳固与经济合理的双重优化目标。结果表明:边坡的加固方案为上部2排锚索长度25 m,中间2排锚索长度20 m,下部2排锚索长度16 m,加固方案的边坡稳定性系数可达1.3以上;锚索应用后可有效确保露天煤矿加固的护坡稳定性。This article systematically analyzes the geological characteristics of the slope in Xinling Open-pit Mine,and explores the application potential of prestressed anchor cable reinforcement as a slope protection measure.Based on the strict theoretical framework of mechanical balance and the consideration of economic benefits,the design parameters of prestressed anchor cable reinforcement of slope are adjusted to achieve the dual optimization objectives of structural stability and economic rationality.The results show that the slope reinforcement scheme after optimization is the upper two rows of anchor cable length of 25 m,the middle two rows of anchor cable length of 20 m,and the lower two rows of anchor cable length of 16 m.The slope stability coefficient of the reinforcement scheme can reach 1.3.The application of anchor cable has a remarkable effect on slope protection,which can effectively ensure the stability of slope protection in open-pit coal mines.
