Abstract
Design and construction of long and large scale tunnels have been developing rapidly in China, whereas the tunnel risk assessment falls behind. Risk assessment has been gradually developed from single-factor evaluation to multi-factor evaluation, and this paper provides a comprehensive review of the disaster risk assessment of long and large scale tunnels during construction and operation stages and discusses their corresponding advantages and disadvantages. The single-factor evaluation for water gushing, collapse, and rock burst are introduced in detail. The main risk assessment methods are also introduced and evaluated, including (fuzzy) analytic hierarchy process, Bayesian networks, and neural networks. Finally, the current research status of tunnel risk assessment is summarized and some suggestions are provided for future development of this field, which are intended to offer some references for engineers and researchers in tunnel engineering.
