High-speed rail risk analysis and control method and high-speed rail risk analysis and control system

The invention relates to the technical field of risk control, and provides a high-speed rail risk analysis and control method and a high-speed rail risk analysis and control system. The method includes the steps: performing cause analysis and effect analysis for hazardous events of a high-speed rail system by the aid of a fault tree and an event tree respectively, enabling m types of causes and n types of effects to form mXn accident sequences, and obtaining risk values of all the accident sequences; and sequencing all the accident sequences according to the risk values to obtain high-risk accident sequences, setting cause and effect control measures aiming at the high-risk accident sequences, and setting further failure control measures for preventing the cause and effect control measures from failing. The method and the system have the advantages that risk of the hazardous events is comprehensively predicated by means of risk analysis of the accident sequences, and the control measures are set by expanding
