摘要:
为探究山区河道型水库中，滑坡涌浪产生的冲击波对重力坝漫坝的影响，运用三维物理模型试验方法，探究近坝库区滑坡涌浪冲击波到达坝前时，坝前首浪最大振幅与涌浪漫坝体积的关系。结果显示，坝前首浪振幅沿坝体两岸向中间减小，坝段中心容易出现最小值；漫坝体积随首浪振幅的增加而增大。研究结果表明：坝前首浪最大振幅与涌浪漫坝体积两者呈正相关关系，漫坝体积受滑坡体角度与滑坡体积影响显著，进而构建漫坝体积计算方法。研究结果能够为大坝安全评估提供一定参考依据。
Abstract:
In order to explore the influence of the landslide-generated impulse waves overtop the gravity dam in the mountainous river-type reservoir,the three-dimensional physical model test method is used to explore the relationship between the maximum amplitude of the first waves in front of the dam and dam overtopping volume when the landslide-generated impulse waves reach the dam in the near dam reservoir area.Research shows that the amplitude of the first waves in front of the dam decreases along the two sides to the middle,and the minimum value easily appears in the centre of the dam section.Dam overtopping volume increases with the increase of the amplitude of the first waves in front of the dam.The research results show that the maximum amplitude of the first waves in front of the dam is positively correlated with the dam overtopping volume,the overtopping volume is significantly affected by the angle of the landslide body and the landslide volume,and the calculation method of the overtopping volume is constructed.The research results can provide some reference for dam safety assessment.
