Progress and prospect of particle finite element method for large deformation simulation in geotechnical engineering

Particle finite element method (PFEM) can effectively simulate large deformation problems in geotechnical disasters such as landslides, debris flows, and dam breaks. In recent years, PFEM has attracted much attention at home and abroad. The research progress of PFEM for large deformation simulation in geotechnical engineering is reviewed. Firstly, the development history and basic idea of the PFEM are introduced. Then, the theoretical progress of the computational theory for PFEM in geotechnical engineering is presented. Finally, the application progress of the PFEM for large deformation simulation in geotechnical engineering is introduced, including collapse and landslide problems, structure–soil coupling large deformation problems, hydromechanical coupled problems, etc. Through the review of the research progress of PFEM for large deformation simulation in geotechnical engineering, the cognition of relevant researchers in this field is deepened, and the development of large deformation simulation theory and engineering application of PFEM for geotechnical engineering is promoted.
