Lining stresses in a TBM-driven tunnel: A comparison between numerical results and monitoring data
The paper deals with the evaluation of lining forces in TBM-driven tunnels in clayey soils. A 3D numerical model has been developed accounting for the main features of the excavation and construction, such as front pressure, cutterhead overcut, shield conicity, lining installation inside the shield, tail void grouting, grout hardening and injection distance from the shield.
