The fluid pressure equation is combined with vibration equation of silicon diaphragm to construct liquid-solid coupling system equations for a micropump.

Based on fluid-solid coupling the landfill contaminant transport model and its simulation;

Casing damage mechanism by applying theory of fluid-solid coupling;

The theoretical model of fluid-solid coupling seepage in low permeability reservoirs;

In order to ensure the safety production under the condition of fully-mechanized caving in Dafoshi coal mine of Binchang mining area,we studied the mechanism of roof water inrush resulted from roof fall and simulated the mining process of the first coal mining face using the solid-liquid coupling material.

A Solid-Liquid coupling mathematical model for permeating consolidation problems under finite deformations is built up, which reflects Solid-Liquid mutual coupling.

Based on the test of mechanical properties of surrounding rocks and underground pressure inspection,analyses mechanism of roadway deformation and large deformation rules through the couple of solid-fluid numerical simulation,concluding that the blot-inject and bolt-shotcrete combined support method is feasible,and provide the theory support for supporting design.
