摘要我国西部大量水库滑坡主要以涌浪形式致灾；采用当前滑坡规范防治涌浪，经济成本巨大，以白鹤滩库区水瓶子1#滑坡为原型；构建了比例尺1∶150的三维原型物理试验场，进行滑坡涌浪降能减浪试验以找寻更为经济的滑坡涌浪降险方案。试验结果表明，当蓄水825 m叠加VIII度地震的极端工况时，滑坡将以7.37 m/s的最大速度冲击白鹤滩水库，产生涌浪的最大波幅为7.59 m，环象鼻岭区域最大爬高超出居民区地面约为3.5 m，将严重威胁超过4.5 km的河道和象鼻岭社区安全。随着削方体积从10.0×104 m3增到47.9×104 m3，滑坡降能减浪效应明显。滑坡造浪能量下降约94.8%，最大波幅和环象鼻岭最大爬高分别下降至4.35和1.73 m，大于1 m的涌浪区域仅分布在滑坡入江区和金沙江对岸区域，滑坡涌浪灾害风险急剧下降。基于此，本文提出并探讨了以滑坡涌浪危险程度为衡量指标的反馈式滑坡涌浪降险工程设计思路和滑坡涌浪降险工程设计安全裕度实现方法，推荐了可大幅降低水瓶子1#滑坡治理经济成本的降险设计方案。滑坡涌浪降险防治思路是对滑坡防治规范的有益补充，尚有待进一步发展和推广应用。

Abstract：A large number of disasters caused by reservoir landslides are in the form of impulse waves in western China. If all landslides that may generate waves are prevented and controlled by current specifications，the economic cost is huge. Taking Shuipingzi #1 landslide in Baihetan reservoir as an example to carry out application demonstration in this paper，a three-dimensional physical prototype model experiment was constructed with a geometric scale of 1∶150，and landslide energy reduction and wave descent experiments were carried out to find more economical landslide-induced impulse wave risk reduction solution. Physical test shows that under extreme conditions of the impounding water level with 825 m above sea level combined with a VIII-degree earthquake，the landslide would slide into Baihetan reservoir with the maximum speed of 7.37 m/s，and the maximum generated wave amplitude would be 7.59 m. The maximum runup around Xiangbiling community is about 3.5 m above the ground，which would seriously threaten the safety of the riverway with the length of more than 4.5 km and the safety of Xiangbiling community. As the removal volume increases from 10×104 m3 to 47.9×104 m3，the effect of reducing energy and wave becomes evident. Wave making energy transmitted from landslide decreases by about 94.8%，and the maximum wave amplitude and the maximum runup around the Xiangbiling decreased to 4.35 m and 1.73 m，respectively. The area with the impulse wave larger than 1 m is only distributed in the landslide course and the opposite bank of Jinsha River，and the risk of landslide-induced impulse wave decreases sharply. Based on this，this study proposed and discussed the feedback design mentality and the realization method of the safety margin of landslide-induced impulse wave risk reduction engineering design，which using the hazard degree of landslide-induce impulse wave as a measurement indicator，and recommended a risk reduction design scheme that can greatly reduce the economic cost of Shuipingzi #1 landslide treatment. The design mentality of risk reduction prevention for landslide-induced impulse wave is a useful supplement of landslide control specification，which has yet to be further developed and promoted.
