“…Bui [12] proposed a computational framework based on meshless smoothed particle hydrodynamics method, which can be used to study the fluid-solid coupling behavior in deformable porous media. Xiao [13] established an analysis model for fluid-solid coupling problems with discrete solid interactions, and proved the stability and accuracy of the model. Yang [14] established a fluid-solid coupling model for the hydraulic fracturing process of fractured shale, which is of great significance to explain the mechanism of shale hydraulic fracturing.…”

This paper confirms that in the u-p coupling model, the calculation results are consistent with the results of the analytical solution. This paper confirms the rationality and feasibility of the u-p-U model solving technology in the u-p-U coupling model. This paper confirms that the calculation results of the two forms are almost the same whenk=10-4m/s and k=10-5m/s. When k=10-3m/s the results of the two calculation forms are slightly different. The finite incremental calculus stabilization method can effectively eliminate the phenomenon of numerical oscillation in the region where the pore pressure gradient changes drastically. The finite incremental calculus stability method has a good stability effect in dealing with the dynamic equation of saturated soil which is difficult to calculate.
