| 摘 要： | 根据清江中下游河流地貌演化与岸坡稳定性的响应关系,将河流地貌演化因子作为岸坡稳定性评价指标,采用层次分析与信息量评价模型相结合的方法,通过地理信息系统实现了清江隔河岩库区的岸坡稳定性定量预测,其预测结果与现实情况比较吻合。研究表明该方法是一种行之有效的岸坡稳定性预测方法,以及河流地貌演化对岸坡稳定性预测具有显著作用。

| Abstract: | According to analysis the geomorphology evolution of middle and lower reaches of Qingjiang River and bank slope stability of response relationship, the river geomorphic evolution factor as bank slope stability evalua-tion index, the analytic hierarchy process and information method were employed to predict bank slope stability. Finally, bank slope stability is quantitatively assessed using the geographic information system for the regional area of Geheyan reservoir on the Qingjiang River;the results were basically consistent with the status of the local disasters. The results indicate that it was an effective method for prediction of bank slope stability, and river geo-morphic evolution was the critical factor for bank slope stability. |
