摘要

滑坡涌浪是影响山区水库安全运行的主要威胁之一，研究V型河道滑坡涌浪的首浪特征和影响因素对库区灾害防治有重要意义.本文使用FLOW3D计算流体力学方法对V型河道滑坡涌浪灾害进行了系统研究.建立了V型河道滑坡涌浪计算模型，考虑滑坡体体积、滑速、河道水深、岸坡倾角、滑床摩擦系数等因素，进行了35组不同工况下的滑坡涌浪数值模拟，获取滑坡入水产生涌浪的过程和首浪高度.将数值模拟结果与经验公式进行了对比，分析不同因素对首浪高度的影响程度.结果表明，河道水深、滑床摩擦系数与首浪高度呈负相关，滑坡体积、入水速度、岸坡倾角与首浪高度呈正相关.各因素对首浪高度的影响程度关系为：入水速度>滑坡体积>岸坡倾角>河道水深>滑床摩擦系数.本文研究为山区水库滑坡涌浪灾害防治提供参考.
