| 中文摘要:岩土锚固是边坡岩土体加固的主要措施。以酒泉钢铁（集团）有限责任公司镜铁山矿黑沟矿区已变形边坡加固工程为例，利用Slide软件进行边坡稳定性分析及支护结构设计计算，对已变形边坡采取预应力地梁锚固+坡顶防渗排水+主、被动网防护+随机锚固的综合治理工程措施，阐明了高边坡预应力锚索地梁的一般程序与方法。实践表明，采用以预应力锚索地梁为主的综合防治措施，对已变形高边坡的变形控制和支护效果较好。 |

| Abstract:Geotechnical anchoring is the main measure of slope rock and soil reinforcement. Take an example of deformed slope reinforcement project in Heigou mining area of Jingtieshan mine, the slope stability analysis and supporting structure design calculation are made by using Slide software, then the comprehensive management engineering measures of groundsill by pre-stressed anchorage + slope top seepage prevention drainage + active and passive network protection + random anchorage are adopted for the deformed slope. This paper illustrates the general construction procedure and methods of the high slope pre-stressed anchor cable groundsill. The practice shows that the comprehensive prevention and control measures based on the pre-stressed anchor cable groundsill are good for the deformation control and the supporting effect of the deformed high slope. |
