ABSTRACT

Although earthquake is an occasional event, it is a great natural disaster for the safety of the railway. Many countries such as Japan, Taiwan, France, Germany and South Korea have established earthquake emergency control systems to mitigate the hazards of railway in earthquakes (Sun et al., 2007; Sun et al., 2011; Lu et al., 2010). China is an earthquake-prone country, thus full consideration should be given to operation risk of the railway designs in earthquake zones when promoting large-scale railway construction. The first earthquake monitoring and warning system has been established in Beijing-Tianjin high-speed rail line in 2011.
