Seismic Vulnerability Analysis of Rock Mountain Tunnel
Seismic fragility analysis is a way to study the vulnerability of structures considering various uncertainties. In the paper, a seismic vulnerability analysis of rock mountain tunnels is proposed. The uniform design method (UDM), a computationally economic method for experiment design, is adopted here. Through the UDM, experiment samples are generated considering variability of the variables. Different tunnel depths, tunnel scales, rock masses, and lining thicknesses are considered. Verified dynamical finite element analysis is carried out to develop probabilistic seismic demand models. The fragility curves are established based on probabilistic seismic demand models. It is concluded that (1) UDM can generate good samples considering different sources of uncertainties; (2) a comparison between the established vulnerability curves and the empirical ones validate the feasibility of the developed methodology.
