摘要: 应用一维数学模型、二维数学模型及混合数学模型,对水库滑坡涌浪灾害进行了分析研究。在此基础上研究了长江三峡库区的两个典型地段黄腊石滑坡及链子崖危岩体。结果表明:若滑坡一旦发生,都将对附近12 km左右范围内人民生命及财产造成相当严重的危害。

Abstract: A research on numerical calculation of landslide surges and their influences was performed respectively by 1-D, 2-D and a combined mathematies models. Applying these models, two typical river stretches, i.e. Huanglashi landslide body and Lianziya dangerous rock mass, in the TGP reservoir area were investigated. The study results showed that if the sliding of dangerous rock mass once happened, it would cause afairly serious harm to the peoples lifes and properties in the range of 12 kmupstream and downstream the landslide..
