Abstract

Abstract: In order to promote the safe operation and safety management of Chinese high-speed railway under the new situation, the safety trend and influencing factors of Chinese high-speed railway were analyzed and summarized. Among them, the lack of high-speed rail safety cognition, bad weather and geological disasters, the influence of the high-speed railway environment and the lagging of the regulation and system construction were the main factors. Under the overall framework of the influencing factors, through on-site investigation and analysis, the key safety hazards in the high-speed railway operation lines were studied, such as roadbed, bridge and tunnel foundation settlement, rail plate cracking or arch, jitter of motor car body, continuous brittle fracture of fastener, sound (wind) barrier, lack of safety protection of high-speed railway and so on. The causes of safety accidents, potential consequences and preventive measures were analyzed and proposed from the aspects of design, construction, operation and surrounding environment. The results show that field practice has verified the accuracy of cause analysis and the effectiveness of preventive measures.

Key words: high-speed railway, safety trend, influence factor, safety problems, causes analysis, measures
