Subdivision of Ground Motion Parameters in Ankang City

Abstract

On the basis of studying the geological environment, seismic environment and geodynamic conditions of the site of Ankang Seismic Zoning Project, this paper divides the seismic statistical area and potential seismic source area, determines the seismicity parameters of the seismic statistical area and potential seismic source area, determines the attenuation relationship of the ground motion of the bedrock in the study area, calculates the seismic risk analysis, and calculates the bedrock. The calculation model of site seismic response analysis is established, the site seismic response analysis is carried out, and the design earthquake ground motion zoning of the site is carried out, which provides a basis for the seismic fortification of the general structure of the site in Ankang seismic zoning.
