摘　　要：为研究西部某水电站水库蓄水后,王家山滑坡的稳定性及其发生失稳破坏以较高的滑动速度进入库区,其形成的涌浪高度和对附近居民或设施的影响。本文采用潘家铮法和美国土木工程师协会推荐公式,计算王家山滑坡失稳破坏的最大入水速度;采用潘家铮法和中国水科院法等经验公式,估算滑坡涌浪高度。通过对比分析,认为潘家铮法计算结果更为合理,推荐采用潘家铮法预测库岸滑坡失稳破坏产生的涌浪高度。In order to study the stability of Wangjiashan landslide after impoundment of a hydropower station in the west of China, and the influence of high-speed sliding into the reservoir area, the height of surge and its impact on residential areas are predicted. In this study, the sliding speed of Wangjiashan landslide is calculated by Pan Jiazheng method and the formula recommended by American Society of civil engineers. The surge height of landslide is estimated by Pan Jiazheng method and the empirical formula of Chinese Academy of hydraulic sciences. Through comparative analysis, it is considered that the calculation result of Pan Jiazheng method is more reasonable, and Pan Jiazheng method is recommended to predict the surge height of reservoir bank landslide.
