摘要：
A numerical simulation is carried out to study the settlement of ground caused by the construction of a shield tunnel. As a high speed railway is just above the tunnel and the differential settlement is limited in 5 mm; it requires high quality of the tunnel construction. The simulation results indicate that the grouting reinforcement to the stratum between the railway and the tunnel is an effective way to control the settlement of ground; and the values of several parameters gained in the calculation can serve for reference in the construction.
