Influence of Water Inrush from Excavation Surface on the Stress and Deformation of Tunnel-Forming Structure at the Launching-Arrival Stage of Subway Shield

Figure 14

Variation of the deformation and internal force of the segment and the internal force of the bolt with the water inrush time. (a) Maximum deformation of the segment. (b) Maximum tensile stress of the segment. (c) Maximum compressive stress of the segment. (d) Maximum tensile force of the bolt. (e) Maximum shear force of the bolt.
