本文提出了一个简单而有效的预测快速灾害性滑坡传播的模型。主要成分是：i）描述固体骨架和孔隙流体之间的耦合行为的一组分层数学模型。在这里，我们将到达一个耦合的深度集成模型; ii）描述流化土壤的行为的流变模型; iii）离散数学和流变模型的数值模型。模型的性能已使用一套基准测试进行评估，包括香港岩土工程处提供的一些测试。
ABSTRACT This paper deals with a simple yet effective model which can be used for prediction of propagation of fast catastrophic landslides. The main ingredients are: i) a hierarchical set of mathematical models describing the coupled behaviour between solid skeleton and pore fluids. Here we will arrive to a coupled depth integrated model; ii) a rheological model describing the behaviour of the fluidized soil; iii) a numerical model to discretize mathematical and rheological models. The model performance has been assessed using a set of benchmark tests, including some provided by the Hong Kong Geotechnical Engineering Office.
