嘉陵江亭子口水电站库区张家湾滑坡变形监测与分析

Deformation Monitoring and Analysis of Zhangjiawan Landslide in Tingzikou Hydropower Station Reservoir Area

极端天气的频繁出现,严重威胁了水电站库区周边居民的人身和财产安全,因此,对库区重点区域进行变形监测,分析监测数据并及时预警,进而为防灾减灾工作提供依据。亭子口水电站库区张家湾滑坡先后采用了“群测群防”、常规及自动化的监测方法,基于2018年7月至2021年12月监测数据分析滑坡的稳定性,监测结果表明:滑坡两侧及后缘较稳定,滑坡中部前缘位移量较大,每年7—9月,变形加速,位移明显。

The frequent occurrence of extreme weather seriously threatens the personal and property safety of residents around the hydropower station reservoir area.Therefore,deformation monitoring is carried out in the key areas of the reservoir area,the monitoring data is analyzed and the early warning is issued timely,so as to provide a basis for disaster prevention and mitigation.The Zhangjiawan landslide in the reservoir area of Tingzikou Hydropower Station has successively adopted"mass measurement and mass prevention",conventional and automated monitoring methods,and analyzed the stability of the landslide based on the monitoring data from July 2018 to December 2021.The monitoring results show that the two sides and trailing edge of the landslide are relatively stable,the displacement of the leading edge in the middle of the landslide is large,and the deformation accelerates from July to September every year with apparent displacement.
