摘　　要：通过模型试验，研究不同类型（粘性、稀性、水石流）和不同规模（Ｐ＝２％、４％）的泥石流在古乡沟堆积扇上的运动和冲淤规律，同时进行防治工程模型试验研究，结合野外调查和资料对比，选择合理的防治工程方案，为工程设计提供可靠的依据和数据。The movement and scour on deposition fan of different types (viscous,diluent and water stone) of debris flow have been studied by model tests.Synthesizing the relevant data of the tests on prevention construction and field investigation,a rational engineering programme against disaster of debris flow has been obtained.The conclusions of this study is of significant reference value for the disaster prevention of the gullies along Sichuan Tibet highway which are similar to Guxiang gully.
