Using radial point interpolation method (RPIM) and considering the precision requirement in wave motion simulation, a lumped-mass RPIM for saturated porous media with clear physical concepts is derived. Combining explicit time integration with the lumped-mass RPIM leads to a decoupled radial point interpolation method (decoupled RPIM) for dynamic analysis without solving algebra equation set. A two-dimensional problem is calculated by the proposed decoupled RPIM, the ordinary RPIM，and the finite element method (FEM). The accuracy and efficiency of these methods are compared, which demonstrate that the proposed decoupled RPIM has comparable accuracy with the ordinary RPIM and the finite element method, but has high efficiency in simulating wave motions in saturated porous media.
