摘要
三峡库区是我国最早系统性地实施滑坡等地质灾害专业监测的区域之一,从2003年三峡水库蓄水至今20a,三峡库区秭归段内已有超过200处滑坡灾害实施了专业监测预警,监测技术方法涵盖了早期的人工监测到近年来的实时自动化监测。文章在介绍三峡库区秭归段内现有地质灾害专业监测技术方法概况基础上,针对以滑坡为主的不同专业监测技术方法进行了系统总结和适宜性分析,并根据斜坡变形阶段和不同变形特征提出了针对性专业监测技术方法选择建议。结果表明:无论是针对斜坡变形阶段还是不同变形特征,GNSS自动地表位移结合自动降雨量监测均是首选技术,然后应根据具体需求和灾害体实际情况,适当增加其他监测技术。研究成果可为更好地优化实施库区后续地质灾害监测提供一定参考。
The Three Gorges Reservoir area is one of the earliest regions in China to systematically implement professional monitoring and early warning for geological disasters such as landslides.Since the impoundment of the Three Gorges Reservoir in 2003,nearly 300 instances of landslide disasters have been recorded in the Zigui section of the Three Gorges Reservoir over the past 20 years.Monitoring techniques have evolved from early manual monitoring to real-time automated monitoring in recent years.Based on an overview of the existing professional monitoring techniques and methods for geological disasters in the Zigui section,this paper systematically summarizes and analyzes the suitability of different professional monitoring techniques and methods.Additionally,it provides recommendations for selecting appropriate professional monitoring techniques based on the stages of slope deformation and various deformation characteristics.The findings reveal that GNSS automated surface displacement monitoring with automated rainfall monitoring is the preferred technology,regardless of the slope deformation stage or the distinct deformation features.Other monitoring technologies should be added as needed based on specific requirements and the actual conditions of the disaster site.The research findings provide valuable references for optimizing the implementation of future geological disaster monitoring and early warning in the reservoir area.
