三峡库区巴东县龙船河库岸塌岸预测及稳定性评价

Reservoir Bank Collapse Prediction and Stability Evaluation of Longchuanhe Reservoir Bank of Badong County in Three Gorges Area

采用卡丘金法、工程地质类比法对三峡库区巴东县龙船河库岸不同成因的土质岸坡、岩土混合质岸坡、软硬相间的岩质岸坡在水库蓄水后的塌岸进行了预测,并采用不平衡推力法对其稳定性进行了计算分析与评价,根据预测评价结果进行的防治方案设计,通过了三峡水库三期蓄水的检验,取得了较好的防治效果。

In order to discuss the bank collapse prediction and the stability evaluation of soil and rock bank of different types and geological structures in Three Gorges area after impounding, the authors predicted the bank collapse width by E. F. Kaqyrrm Method and geoengineering analogy graphic method, and calculated and evaluated the stability of the Longchuanhe reservoir bank through imbalance-thrust-force law. The engineering prevention measures based on them have thus been proposed and proved to be successful in practice.
