Through engineering example and using the FEM software GTS, water-rich loess tunnel excavation is analyzed without or with the grouting-reinforcement effect and different permeability coefficient of grouting-reinforcement structure. Influence of flow field characteristics and displacement field characteristics caused by variation of grouting-reinforcement structure permeability coefficient in ordinary water level was analyzed. The results show that the permeability coefficient of grouting-reinforcement structure is play an important in the seepage path, pore water pressure and seepage velocity. It also influence in the displacement of surrounding rock. Designs of grouting-reinforcement structure of water-rich loess tunnel should consider impact of seepage-stress coupling effect. First, the waterproofing effect of grouting-reinforcement structure should be considered to, otherwise, it should avoid that the pore water pressure increasing by increase of waterproofing effect of grouting-reinforcement structure, the soil shear strength reducing.
