Other Abstract


As a kind of multiphase mixture medium,the debris flow has the complicated physical processes and kinetic characteristics. The development of numerical modeling methods for simulating debris flow is accompanied by numerical computing methods and physical computing models.Numerical modeling methods based on the physical processes provide an effective measure to explore the mechanism of complex physical phenomena for debris flow.Numerical modeling methods for the debris flow dynamic problems were reviewed;the characteristics and applicable scopes of different numerical modeling methods including continuous medium,discrete medium and mixture medium computing methods were analyzed;the popular used numerical modeling software for the analysis of debris flow and their characteristics are introduced;the development trends of numerical modeling methods for the debris flow dynamic problems were discussed.The results show that traditional computing methods based on mesh have considerable development and application history,but have problems such as mesh disordering when dealing with large deformation and fast transportation of free surface flow;when dealing with the above problems,the computing methods based on particle do not need mesh partition and maintenance, and easily locate the position of free surface and interface of phases,but have difficulties such as applying boundary conditions;mixture medium computing methods have important role when discussing the interaction mechanism of solid particles with fluid phase in small scale.
