水布垭水电站滑坡工程治理监测实况

Treatment and Monitoring of Land-sliding project of Shuibuya Hydropower Station

湖北省清江水布垭水电站为高面板堆石坝,位于大坝下游的古树包滑坡体,于2001年1月发生了整体滑坡。由于安全预报及时,滑坡体上居住的300多人得以安全撤离,无一人伤亡。滑坡造成大坝施工交通公路被迫一度中断。经建设、设计和施工单位的共同努力,对滑坡进行了行之有效的工程加固和生态环境防护措施。通过深部位移监测反映,滑坡体目前压缩变形较大,未发现新的滑动面。滑坡体目前处于相对稳定状态。

The Shuibuya Hydropower Station in the Qingjiang River in Hubei Province is a high concrete facing rockfill dam. The Gushu Landslide Body is located in the downstream of the dam and occurred integral landslide in January of 2001. Because the safety forecasting is in time, no person died and more than 300 persons safely evacuated from the sliding-body. With the efforts of construction, design and construction units, the landslide body has been reinforced effectively with ecological environment protection measures. Through the deep monitoring of displacement, it showed the landslide body compressive deformation is big at present but no new sliding surface occurs. This landslide body is in a relative stability state at present.
