| Abstract: | By considering the seismological condition, seismicity and ground motion atlenuation relations of bedrock in Nanjing and its neighboring area, the peak ground motion accelerations and the acceleration response spectra of different excellence probabilities of bedrock in the Hexi area of Nanjing city were given. According to the in situ testing and laboratory testing of soil layer dynamic parameters of a typical soft soil site, the site effect and design ground motion parameters of the site for excellence probabilities 63, 10 and 3 percent in 50 and 100 years were studied. The results are also useful to the seismic design of engineering in other site of the area. |
