Abstract This paper pointed out the influence of dewatering settlement on the structure of shield inclined shafts in the aquifer. The dewater settlement laws of aquifer were analyzed，and the compression ratio of aquifer was selected as the parameter to represent the dewater settlement performance. The load and deformation which the shield segment suffered during aquifer dewatering were studied，and the cantilever beam model under even load was built. The elastic-plastic analytical solutions of the stress and deformation of the shield incline shafts were given through the equivalent continuum model. At last，the mechanical model proposed in this paper was applied to the shield inclined shaft in Shenhua Xinjie coal mine，and the stress and deformation of the incline shafts due to dewater settlement of aquifer were worked out.

Key words： tunnelling engineering shield tunnel incline shafts dewater settlement longitudinal deformation
