Some Disposing Suggestions for the Lacustrine Sedimentary Soft Soil in the Seismic Design of Buildings

Li Hongguang;National Earthquake Response Support Service;  
Lacustrine sedimentary soft soil has a relationship with the seismic design parameters of site's soil types of construction,under seismic loading,the soil stress-displacement response in the nonlinear sphere,the equivalent linearization method commonly used will seriously underestimate the peak ground acceleration.In order to show the extent of the deviation with equivalent linearization method,we choose a typical borehole and use a direct time-domain integral method to analyze the site responses under the excitation ground motions.In comparison with the equivalent linearization method,the soil may enter nonlinearly in large range and the equivalent linearization will no longer be applied under the big earthquake.Based on the above analysis,some solutions to the determination of design ground motion for engineering sites with deep soft surface layers are proposed and discussed.
