Study on the Relationship of Seismic Design Ground Motion at Different Fortification Levels in the Xinjiang Region
Tang Lihua
Abstract:
The seismic risk analysis results of 79 cities in Xinjiang are presented, and the bedrock peak ground accelerations under three seismic levels and their ratios are discussed. Then, the relationship between earthquake environments and the seismic risk analysis results of different exceeding probabilities are researched. The results show that minor and major earthquake motion parameters calculated from moderate earthquakes do not have a consistent probability and the ratio of bedrock peak accelerations under different exceedance probabilities are closely correlated with earthquake environments.
Key words:  Fortification level  Design seismic ground motion  Xinjiang
