Summary of Research on Seismic Vulnerability of Tunnel Structures

Long and large tunnel structures are one of the main lifeline projects, their seismic damage should be given great attention. In order to understand performance tunnels other underground structures, this paper introduces origin development theory input methods long definition vulnerability, summarizes key factors vulnerability research, including site conditions, earthquake types, structural uncertainties, strength indexes, indexes. Finally, based on shortcomings studies, future is presented.
