英文摘要： High-speed railway plays an irreplaceable role in the process of social development and economic construction.High-speed railway signal system is a complex system, which improves and ensures the effectiveness and credibility of independent safety evaluation of high-speed railway signal system, facing many problems such as “highly systemic”, “complex technical characteristics”, and “lack of standardized scientific method”. This project is going to construct the high-speed railway signal system accident analysis model, systematically reveal induction mechanisms, formation mechanisms and accident propagations which related to some aspects such as human-machine-environment in high-speed railway system; improve the safety risk analysis method of high-speed railway signal system, construct the top risk database of high-speed signal core system;build the high-speed signal evidence chain model, develop the evidence chain dynamic tracking and management technology suiting to the high-speed railway signal system safety assessment, and develop the corresponding supporting tools; study the general safety demonstration model of high-speed railway signal system, develop the evaluation technology of safety assessment credibility;build the safety testing requirements model of high-speed railway signal system, establish the third party safety validation testing technology demonstration platform.This project can improve the overall safety level of high-speed railway signal system, and ensure the efficient and safety operation of the high-speed train.
