• Effects of Surface Soil Structure on Liquefaction Damage in Mihama Ward of Chiba City

抄録

In order to evaluate the effects of surface soil structure and the amplification characteristics on the liquefaction damage in Mihama ward of Chiba city during the 2011 Great East Japan earthquake, microtremor measurement and seismic ground motion observation were conducted. The shear-wave profile models of divided 50m square grids in the ward were estimated based on lots of borehole logs. The equivalent linear analysis was conducted using the estimated profiles and the seismic ground motion record of the main shock. The distribution of estimated maximum shear strains of sand layers shows good agreement with the liquefaction damage distribution.
