| 本文通过对福建省上杭县紫金山金铜矿露天采场东帮进行综合监测，结合边坡雷达预警数据、GNSS监测数据、内部位移计监测数据，分析因降雨引起的采场东北帮820~868边坡在重力及雨水冲刷的双重作用下突破临界约束而出现的突然性垮塌。边坡雷达有监测到位移加速变形的趋势，但未及时发出预警。利用综合监测手段，更进一步准确分析高陡边坡。为解决边坡雷达预警问题更进一步监测边坡局部垮塌变形，本文设置预警分区，对采场东北帮820~868边坡进行区域圈定，设置更为敏感的预警阈值。减小圈定区域边坡雷达监测黄色预警和红色预警的短期预警值、长期预警值和预警面积，对曾经出现垮塌区域设置预警分区，从而做出更加准确的预警，显示监测数据波动变化的趋势，为类似高陡露天边坡监测提供参考。 |
| 英文摘要: |
| Based on the comprehensive monitoring of the east side of the open-pit stope of Zijinshan gold and copper mine in Shanghang County， Fujian Province， combined with the slope radar warning data， GNSS monitoring data， and internal displacement meter monitoring data， this paper analyzes the sudden collapse of the 820~868 slope in the northeast side of the stope caused by rainfall under the dual effects of gravity and rainwater erosion. The slope radar has monitored the trend of displacement acceleration deformation， but it has not issued an early warning in time. Using comprehensive monitoring methods， further accurate analysis of high and steep slopes. In order to solve the problem of slope radar early warning and further monitor the local collapse deformation of the slope， the paper sets up the early warning zone， delineates the area of the 820 ~ 868 slope in the northeast of the stope， and sets a more sensitive early warning threshold. The short-term early warning value， long-term early warning value and early warning area of yellow early warning and red early warning of slope radar monitoring in the delineated area are reduced， and the early warning zoning is set up for the collapse area， so as to make more accurate early warning and show the trend of fluctuation of monitoring data， which provides reference for similar high and steep open-pit slope monitoring. |
