The discrete element method (DEM) provides an effective approach to analyse the large deformations and discontinuous problems in geotechnical engineering. In this paper, to improve the capability of DEM for seismic response analysis of rock masses, the problem of boundary setting in DEM is systematically investigated. Three typical dynamic boundary conditions are reviewed and introduced into DEM....
In this paper, the seismic stability of the #1 surge chamber of the Baihetan hydropower plant, which is influenced by a large dominating geological discontinuity [the interlayer shear weakness zone (ISWZ) C2)], is studied. An advanced, nonlinear, continuously yielding (CY) model was adopted to describe the complex mechanical properties of ISWZ C2. This model considers a power function type, normal...
