Abstract

The invention provides a high-speed railway post-earthquake operation safety assessment method, device and equipment and a readable storage medium, and relates to the technical field of high-speed railway operation, and the method comprises the steps: obtaining first information and second information in real time, and the first information comprises a seismic oscillation acceleration time travel curve collected by a seismic station; calculating an earthquake end moment according to the first information; dividing the second information into historical moment information and post-earthquake data information according to the earthquake ending moment; calculating according to the historical moment information and the post-earthquake data information to obtain a structure state coefficient change rate and a structure stability coefficient change rate; and judging the safety state of the structure according to the change rate of the state coefficient of the structure and the change rate of the stability coefficient of the structure. The earthquake ending moment is accurately calculated according to the earthquake acceleration time travel curve, and the data is divided into the data at the historical moment and the post-earthquake data based on the earthquake ending moment, so that the purpose of accurately separating the data is achieved; and the safety state of the structure is calculated on the basis.
