The triaxial compression tests were carried out to study the strength and creep property of grouted and ungrouted sand. Then by using those experimental results, elast-plastic finite element methods were performed and predicted the deformations around the tunnel and ground surface, in each tunneling construction stages, with changing the influence of grouted area around the tunnel. In those analysis, Mohr-Coulomb model was used, and, by limiting excavation stage, time dependent Creep model was also used and compared with these models.
