| 摘 要： | 库岸稳定性取决于最大崩塌临界机制的驱动力和抵抗力的平衡,二者的平衡又取决于库岸边坡形态、岩土组成、水流浪涌特征、植被覆盖等.边坡形态是库岸稳定性的基本条件,主要指标有坡度、岸高及坡面形态.以三峡库区忠县石宝镇段为例,利用BSTEM模拟分析库岸边坡形态对其稳定性的影响,从而得到如下结论,研究库岸坡形形态对其稳定性的影响,...

| Abstract: | The stability of a reservoir bank depends on the balance of forces,motive and resistive,associated with the most critical mechanism of failure.Many mechanisms are possible and the likelihood of failure occurring by any particular one depends on the geometry and structure of the bank,the engineering properties and vegetation of the bank material,the hydraulics of flow in the adjacent channel and climatic conditions.Bank geometry is the postulate,and it includes bank angle,bank height and bank profile.In this paper,Shibao town Zhongxian Country of Three Gorges section was taken for example,and then analysis the impact of reservoir bank geometry on the stability via BSTEM model.This will be help to study the risk of soil erosion of reservoir bank,and have a guiding role in prevention and control measures. |
