| Abstract: | Taking the site of terminal building of Pudong International Airport Phase 2 as an example,the seismic responses of soil layer with deep deposits have been calculated using both two dimensional and one dimensional models respectively,and the effects of the ancient river bed buried in the engineering site on the seismic parameters are discussed.Moreover,the seismic responses of the soil layer are analyzed under the excitations of the seismic traveling-wave and uniform input respectively for comparing the dif... |
