Seismic safety evaluation refers to the use of advanced seismic risk probability analysis methods based on the in-depth study of the specific construction site and its surrounding areas in terms of seismic geological conditions, geophysical field environment, seismic activity law, modern topographic deformation and stress field, etc, The ground motion parameters (acceleration, design response spectrum, ground motion time history, etc.) and corresponding data required by the corresponding engineering planning or design at a certain probability level are given scientifically.
