摘　　要：为了研究三峡库区岩体滑坡沿程涌浪的传播特性,开展了大缩尺比的水库模型试验。将水库模型分为滑坡断面、直道、弯道及过弯直道等4个区域,共布置了25个测点;对比分析了各测点水位值h的变化规律,探讨了岩体滑坡沿程涌浪的最大波高H max、平均波高H av的传播和衰减规律。结果表明:滑坡断面、直道和过弯直道3个区域涌浪的最大波高、衰减程度随着传播距离的增加而减小;滑坡断面区域涌浪波高最大且衰减最快,其他3个区域涌浪波高值相近,波高衰减情况相似。In order to study the propagation characteristics of landslide-generated surge along the river in the Three Gorges Reservoir area,a large-scale reservoir model test was carried out.The reservoir model was divided into four regions:landslide section,straight section,curved section and straight section beyond bend.A total of 25 measuring points were arranged.The variation law of water level h at each measuring point was compared and analyzed.The propagation and attenuation laws of the maximum surge height H max and average surge height H av of the landslide-generated surge along the river were discussed.The results show that with the increase of propagation distance,H max and attenuation degree of surge decrease in three regions—landslide section,straight section and straight section beyond bend.The surge height of landslide section is the largest and the attenuation is the fastest,and the other three regions have similar surge height and similar attenuation.
