Abstract
Historical catenary trip fault data of China high-speed railway (HSR) revealed that the risk of catenary trip varies distinctively in different time periods and different regions, and catenary trip fault risk has obvious characteristics of time–space differences. In order to represent and quantify the characteristics of risk, this paper proposes a risk index system for catenary lines of HSR considering the characteristics of time–space differences. First, the characteristics of the catenary trip risk and the corresponding reasons are analyzed. Second the risk index system is established from the perspectives of time and space differences. Subsequently, the proposed risk index system is applied to the benchmark data taken from a railway administration in China related to catenary trip records in 3 years. The results of the risk indices are relevant information which can reveal the time–space differences of catenary trip risk, and reflect the influence of external environmental factors as well as catenary’s ability of disaster prevention and resilience. This uniform and quantitative information is helpful for the management of the catenary operation risk.
