| Abstract: | his paper discusses the effects of the wall height-radius ratio and the filled soil on the effective mass of the artificial Island in case of horizontal seismic action by model vibrational experiments.The effective mass coefficient of a circular artificial Island under seismic load is provided for the practical engineering structural design. The calculation methods of dynamic pressure of soil and the author' s view of calculating dynamic pressure of soil for a circular artificial Island are presented and the natural frequencies of the artificial Island model are calculated by the energy method. |
