Shake Table Test on Seismic Response of Non-Free Liquefiable Site
The evaluation of seismic site response is particularly useful for geotechnical engineers involved in the design of foundations in liquefiable sites. The shake table test is aimed at observing and analyzing the site response under different effects of shaking frequency and intensity. The soil profile consisted of a clayey layer over liquefiable sand over clay. The shaking sequence applied to the model was a small scaled, small and large El Centro motion (amax, baseapprox.0.15g, time interval 0.006 sec; amax, baseapprox.0.15g, time interval 0.02 Sec; amax, baseapprox.0.50g, time interval 0.02 Sec). The aim is to observe and analyze the site response under different shaking frequencies and intensities. The tests reproduced the macro-phenomena of soil liquefaction induced by earthquake. The excess pore water and peak accelerations under different shaking frequencies and intensities are discussed. The research has enhanced our current understanding on the mechanism of seismic soil-pile interaction during the development of liquefaction.
