Description

technical field

[0001] The invention relates to the technical field of earthquake engineering, in particular to an earthquake safety evaluation computing device and computing method. Background technique

[0002] The site seismic safety evaluation work is based on the comprehensive evaluation of the site's regional seismic environment, including regional and near-field seismic geology and seismic activity, and local site seismic engineering geological conditions, through the development of seismic hazard calculations, ground motion Synthesis and calculation of site seismic response to determine site ground motion parameters and provide a basis for engineering anti-seismic fortifications.

[0003] With the continuous increase in the breadth and depth of my country's engineering construction, the seismic environment and local site conditions for major projects and infrastructure construction are becoming more and more complex. For example, the long-span Nanjing Yangtze River F...
