Abstract: For geohazards and geotechnics, numerous problems involve large deformation, such as the installation of foundations, landslides, debris flow, collapse of underground structures, and the formation of sinkholes (Barandiarán Villegas, 2018). Benefitting from the sustained development of computing power, numerical simulations have become useful analytical methods in geomechanics and related fields. This special issue contains original research articles on the application of numerical methods to large deformation analysis of geohazards and geotechnics. Focal points of the issue include innovative uses of: (1) mesh-based methods, (2) mesh-free particle methods, (3) mesh-based particle methods, (4) discontinuous numerical methods, and finally (5) practical applications of the above techniques, e.g. case studies and benchmarking exercises.
