Abstract Based on the Mindlin displacement solution and the stochastic medium theory，the vertical displacement of soil caused by the construction of the quasi-rectangular shield was derived considering the bulkhead additional thrust，the friction between the shield and the soil，the additional grouting pressure and the soil loss. A convergence mode coefficient ? at tunneling face and a revised formula of longitudinal loss rate were presented. The predicted vertical displacements agree with the measured values and reflect the process of uplift and gradual settlement of longitudinal settlement curve in the vicinity and at rear of the excavation front. The ground settlement increases with the depth. The soil settlement on two sides of the tunnel axis is larger than that above the axis and the settlement curve is W-shaped. The method proposed in this paper can also be used to analyze the cases that pressure of soil chamber is unequal. In such cases，the settlement curve in front of the excavation surface is no longer symmetrical. The bulkhead additive thrust decreases and the surface settlement increases in front of the excavation face.

Key words： soil mechanics quasi-rectangular shield multiple factors vertical displacement of soil convergence mode of tunnelling face stochastic medium theory Mindlin solution
