The frequency of debris flow disaster in the disaster area is significantly increased after the "5·12" earthquake. In order to reduce the impact of disasters and economic losses, most of the prone debris flows have been treated. Retaining dam is a widely used measure in the prevention of debris flow. Firstly, this paper propose and apply the wing wall type dam against debris flow based on the geological conditions of Tangfanggou debris flow compared to the traditional linear type gravity dam. Then finite element software ANSYS is used to simulate and calculate the wing wall type dam under the overall impact of debris flow, and analyzed the deformation and force characteristic of the dam. Lastly, the dam was optimum designed combined with numerical simulation results in order to ensure the long-term effectiveness of the dam, and the research results can provide reference for similar engineering prevention of debris flow.
