TITIL : Slope failure analysis by MPS method (Moving Particle Simulation) and itsaleatory uncertainty
ABSTRACT :After the formulation of MPS method for geotechnical material is outlined, slope failure simulation by MPS method, experiment of rock falling and its simulation by DEM are shown. The uncertainties involved in these strong nonlinear simulations and experiment are discussed. The features of the uncertainty are inferred as follows. In weak nonlinear or linear behavior, the output uncertainty is proportional to input uncertainty. In strong nonlinear behavior, the output uncertainty is constant irrespective of uncertainty level of input data when the input uncertainty is less than certain level.
