摘要: 平庄西露天煤矿工作帮反倾逆层边坡岩层断层构造作用明显,滑坡灾害危险程度高。为了实时掌握滑坡体变化状态,基于下滑力大于抗滑力这一滑坡发生的充分必要条件,采用具有滑坡灾害加固—监测—预警一体化功能的滑动力远程监测预警系统装备,实现了滑动力感知、传输、分析和监测预警的全过程。在该滑坡区域布设滑动力监测站点和位移监测站点,近3个月的监测结果表明:滑动力远程监测预警系统运行效果良好,实现了对“07-0118滑坡”各阶段的监测预警,且滑动力监测效果优于位移监测,验证了该系统的先进性和实用性。该系统的成功应用为其他类似边坡的监测预警提供了技术方法和实践依据。

Abstract: Pingzhuang West open pit coal mine landslide is anti-inclined slope rock inversion layer with obvious fault structure and high level of landslide hazards.In order to grasp the real-time landslide state,the sufficient and necessary conditions of landslides is proposed based on the sliding force greater than the anti-sliding force.The sliding force remote monitoring and warning system with reinforcement -monitoring-warning integration function was adopted to realize the process of sliding force sensing,transmission,analysis,monitoring and early warning.Sliding force monitoring points and displacement comparison monitoring points are laid in the landslide area.Through continuous monitoring of regional landslide for nearly 3 months,the results showed that the sliding force remote monitoring and warning system is running well.All monitoring and early warning stages of the “07-0118 landslide” have been realized,and landslide sliding force monitoring is better than that of displacement monitoring,which verifies the advancement and practicality of the system.The successful application of this system provides the technical method and practical basis for other similar slope monitoring and warning.
