Abstract. For the hydromechanically coupling of solid-fluid porous media, this study presents an explicit stabilized two phase MPM formulation based on the one-point two-phase MPM scheme. To mitigate the spurious pore pressure and maintain the numerical stability, the stabilized techniques including the strain smoothing method and the multi-field variational principle are implemented in the proposed formulation. The strain smoothing technique is used to smooth the volumetric strain rate, and the calculation of the pore pressure increasement at particles is based on the multi-field variational principle. Four numerical examples are performed to evaluate the performance of the proposed formulation. With its effective and easy implemented stabilized techniques, the proposed formulation provides stable and reliable outcomes that well align with analytical solutions and results from other approaches, offering extensively validation that the proposed two phase MPM formulation is an effective and reliable approach for the simulation of solid-fluid porous media under both static and dynamic conditions.
