Research on the Algorithm for Composite Lining of Deep Buried Water Conveyance Tunnel [PDF]
Advances in Civil Engineering, 2021 Composite lining of deep buried water conveyance tunnel for bearing high internal water pressure is a new type of applicable structure. However, up to date, no effective method is available to calculate the stress of the structure. In this paper, a simplified algorithm, which can be used to calculate the stress distribution of composite lining ...

Analytical Elastoplastic Solutions for Deep-buried Circular Tunnels Under Asymmetric Load [PDF]
American Journal of Civil Engineering, 2021 The elastoplastic analysis of the surrounding rock of a circular tunnel is a very classic rock and soil mechanics problem. Previous scholars usually studied the situation under axisymmetric load, and they usually did not take the non-axisymmetric load distribution under the influence of ground stress and lateral pressure into account, which greatly ...
