【摘要】：通过收集国内外边坡监测技术的相关资料,介绍了露天采场高陡边坡稳定性监测的现有技术手段,总结了包括表面位移监测、深部位移监测和深部滑动力监测等各类技术的主要特点和存在问题。进一步对金属非金属露天矿山采场边坡监测技术的规范要求进行了简要论述。综合分析后提出,未来应基于区域形变和深部滑动力监测技术,以滑坡地质灾害远程实时监测预报技术及装备体系为研究方向。通过采用多源信息融合技术,以滑动力监测和边坡表面位移监测为主导,辅以其他监测方法,构成一个深部和浅部联合监测的立体网络系统。采用模块化设计方案,根据现场环境灵活增减监测子系统,可提高露天采场边坡稳定性监测预警的准确性与时效性。
[Abstract]:By collecting the relevant data of slope monitoring technology at home and abroad, this paper introduces the existing technical means of monitoring the stability of high and steep slope in open pit stope, and summarizes the monitoring of surface displacement. The main characteristics and existing problems of various technologies, such as deep displacement monitoring and deep sliding force monitoring. Furthermore, the standard requirements of stope slope monitoring technology in metal and non-metallic opencast mines are briefly discussed. After comprehensive analysis, it is proposed that the remote real-time monitoring and prediction technology and equipment system of landslide geological hazards should be based on regional deformation and deep sliding dynamic monitoring technology in the future. A three-dimensional network system for deep and shallow joint monitoring is constructed by using multi-source information fusion technology, dominated by sliding force monitoring and slope surface displacement monitoring, supplemented by other monitoring methods. The accuracy and timeliness of slope stability monitoring and early warning in open pit can be improved by using modular design scheme and flexible increase and decrease monitoring subsystem according to the field environment.
