Abstract

The present invention provides a method, device, equipment and readable storage medium for post-earthquake operation safety assessment of high-speed railways, and relates to the technical field of high-speed railway operation, including real-time acquisition of first information and second information. The first information includes data collected by seismic stations. Earthquake acceleration time history curve; calculate the end time of the earthquake according to the first information; divide the second information into historical time information and post-earthquake data information according to the end time of the earthquake; calculate the state of the structure based on the historical time information and post-earthquake data information coefficient change rate and structure stability coefficient change rate; according to the structure state coefficient change rate and structure stability coefficient change rate, the safe state of the structure is judged, and the present invention accurately calculates the end time of the earthquake according to the seismic acceleration time history curve, and uses this as a The basis divides the data into historical data and post-earthquake data to achieve the purpose of accurate data separation, and calculates the safety status of the structure on this basis.
