摘要：

This paper presents the numerical modelling of one and two dimensional poroelastic solid flows, using the Material Point Method with double point formulation. The double point formulation offers the convenience of allowing for transitions in the flow conditions of the liquid, between free surface flow and groundwater flow. The numerical model is validated by comparing the solid flow velocity with the analytical solution. The influence of the Young's modulus on the solid flow velocity is discussed for both one and two dimensional analysis cases. It is shown that the solid stiffness has an effect on the poroelastic flow velocity, due to swelling and bending for the one and two dimensional cases, respectively. (C) 2017 The Authors.
