摘要提出盾构施工长距离斜井后，煤层采动引起的上覆地层疏排水对盾构斜井管片结构产生影响。通过分析含水层疏排水沉降规律，选定含水层疏排水后土层压缩比作为评价含水层疏排水性质指标。分析疏排水过程中，含水层内盾构斜井结构的受力和变形方式，建立均布荷载下的悬臂梁模型。采用盾构隧道纵向等效连续模型，得到盾构斜井最外侧接头螺栓处于弹性或塑性时应力和变形的解析解。最后，运用本文所提出的力学模型，计算神华新街矿区含水层疏排水引起的盾构斜井衬砌结构应力和变形。

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
