The invention relates to the technical field of
seismic damage assessment, and provides a
seismic damage assessment method and
system based on a
gas pipeline and seismic oscillation
time history data, and the method comprises the steps: obtaining
gas pipeline parameters and actual measurement seismic oscillation
time history data of a target region, carrying out the preprocessing of the data, obtaining to-be-assessed data, and improving the
data accuracy; a
gas pipeline model
library is constructed, historical seismic oscillation
time history data are collected, a training sample set is obtained through calculation based on the historical seismic oscillation time history data and the gas pipeline model
library, an earthquake damage evaluation model is obtained through training, and the evaluation accuracy and comprehensiveness of the earthquake damage evaluation model are guaranteed. Inputting the to-be-
evaluated data into the
seismic damage evaluation model, generating a damage index of the target area, obtaining a seismic damage
evaluation result according to the damage index, and ensuring the real-time performance of the seismic damage
evaluation result; the geographic position information of the target area is obtained, and the thermodynamic diagram for visually displaying the distribution condition of the seismic damage severity of the gas pipeline is generated based on the geographic position information and the seismic damage
evaluation result corresponding to the target area, so that timely maintenance and rescue are facilitated.
