三峡库区重庆市万州区塌岸现状调查

The Geological Survey on Existing State of Reservoir Bank Collapse Occurred in Wanzhou,Chongqing

水库塌岸是影响三峡水库工程成败的重大地质问题。通过对三峡库区重庆市万州区当前蓄水位下的塌岸现状进行地质调查,查清塌岸段工程地质条件,总结概括了各塌岸类型和特点,同时调查统计了相关的塌岸预测参数。这些工作不但对万州区塌岸预测防治工作提供了地质基础,还可为库区其他地区的塌岸调查防治工作提供良好借鉴。

Reservoir bank collapse is an import geological problem which should have an effect on Three Gorges Reservoir Project. The geological engineering conditions of bank being collapsed are obtained clearly, and the styles and properties of various reservoir bank collapse are generalized through geological survey on existing state of reservoir bank collapse occurred in Wanzhou, Chongqing. Furthermore, we investigated and measured the relational parameters to predict soil or rock bank collapse and recession in field. All of this work can not only give a geological foundation for the prediction and prevention of reservoir bank collapse in Wanzhou region, Chongqing, but also offer good reference to the survey and prevention about reservoir bank collapse in other reservoir area.
