ANALYSIS OF GROUND MOTION PARAMETERS AND GROUND LIQUEFACTION PREDICTION USING GIS FOR KUNMING BASIN, CHINA

摘要

In this paper the geological structure and earthquake activity nearby Kunming Basin, Yunnan, China, have been studied. Different ground motion attenuation models used in Japan and in Yunnan, China, have been reviewed, and quantitative comparisons between the models have been made. The zonation of peak horizontal acceleration corresponding to a seldom happened earthquake and the zonation of the characteristic period of the seismic response spectrum of the basin have been suggested. To analyze ground liquefaction, the liquefaction prediction models popular in China and Japan have been briefly introduced. A GIS-based liquefaction prediction system has been developed by the authors. With the aid of the liquefaction prediction system the ground liquefaction risk of the basin due to the seldom happen earthquake has been clarified.
