N2 - Numerical analyses are widely used to perform a detailed analysis of the tunnel excavations. During the tunneling, parameters such as grouting, overburden, and lining property affect the magnitude and shape of ground surface settlement. By using the measurement data of a shield tunneling excavation case in Japan, the authors tried to investigate the effects of influencing parameters on the ground surface settlement. Furthermore, bending moment, axial force and vertical displacements of tunnel are calculated and compared with the field measurement data. Ground settlement trough is analyzed and compared with the other cases of tunneling in previous literatures. The numerical analyses are conducted in two cases of taking consideration of buoyancy force and without buoyancy force. The accuracy of the numerical analysis is checked by comparing the numerical results with the field measurement data.
