Tunnelling underneath the existing tunnels are very common these days. It is obvious that the under-crossing tunnelling will affect and even damage the existing tunnels. An analytical method is proposed in this paper to better understand the effects of the under-crossing tunnelling on the existing tunnel. The existing tunnel is modeled as a Timoshenko beam lying on a Kerr foundation. The validi…
When designing a shield tunnel, there is often a need to carry out mechanical tests on tunnel lining joints to obtain joint stiffness. As tunnel excavation goes deeper, the moment and axial force acting on the lining segments increase, which requires a more rigid backup frame and a stronger foundation for the traditional testing setup. A new testing setup, named as Compression Steel Butterfly…
