滑坡涌浪是一种危害较大的次生灾害，会对人民的生命财产安全造成重大威胁。为探究滑坡涌浪在不同场域的涌浪水波特性，及时发现危害并采取防范措施，对滑坡涌浪全程进行数值模拟。本研究通过CFD软件FLOW-3D建立滑坡涌浪数值模型，并与经典滑坡涌浪试验对其模拟精度与有效性进行验证，数值模拟涌浪首浪高度与物理模型试验结果一致性较好，数值模拟能反映滑坡涌浪传播的整个过程。基于数值模型，制定关于了滑坡体密度、滑坡体体积及滑坡体初始入水特征的27组数值模拟试验。结果表明：近场涌浪回弹及首波波谷出现时间与滑坡体密度呈负相关；近场涌浪首波势能占全程涌浪势能的70%左右；远场涌浪周期...

As a secondary disaster with great harm,landslide surge poses great threats to people’s life and property safety.In the aim of discovering hazards and taking preventive measures,the whole process of landslide surge wave was simulated numerically to explore the characteristics of surge waves in different fields.A numerical model of landslide surge wave was established by CFD Flow-3D.The accuracy and effectiveness of the model were verified by classical landslide surge wave test.The height of the first wave simulated by the numerical simulation ...
