青走道水库库岸稳定性评价及蓄水后塌岸预测

Stability Evaluation of Qingzoudao Reservoir Bank and Bank Collapse Prediction after Water Storage

在查明洮河青走道水库库区基本地质条件的基础上,对岸坡地质结构特征进行了总结,并通过室内外试验资料结合相关工程经验确定了各种力学参数和各岩土层的水上和水下稳定坡角;根据岸坡地质结构特征和库岸变形破坏特征,对岸坡稳定性进行了分类评价;并估算了水库蓄水后短期塌岸量和最终塌岸量。

On the basis of ascertaining the basic geological conditions of Qingzoudao Reservoir area of Taohe River, the geological structure characteristics of the bank slope are summarized, and various mechanical parameters and water and underwater stable slope angles of various rock and soil layers are determined by combining indoor and outdoor test data with relevant engineering experience. According to the geological structure characteristics of bank slope and the deformation and failure characteristics of reservoir bank, the bank slope stability is classified and evaluated, and the short-term bank collapse and final bank collapse after reservoir impoundment are predicted according to the formula method.
