Static and Dynamic Analysis for Ovaling Deformation of Circular Tunnels under No-Slip Conditions
Many underground structures have witnessed great damage in recent earthquakes. Thus underground structures in earthquake prone zones should be designed to withstand both static overburden loads and earthquake loads. In this paper, different closed form solutions for the analysis of the tunnel response, are considered as developed on the basis of the theory that the stress increment due to seismic loading can be assessed through a correct estimate of free-field deformation, while the internal forces of tunnel linings subjected to overburden loads can also be estimated through an assumption of far-field stress using the developed solutions. Numerical studies have been performed to validate the available analytical solutions.
