In the case of discussing the amplification of ground motion of deposits, including the liquefiable loose sand layers, it is important to consider the non-linearity depend on change of overburden pressure due to rising of excess pore water pressure added to the non-linearity depend on shear strain of the ground. In this paper, effect of excess pore water pressure on amplification of ground motion, in particular, maximum acceleration and response spectrum ratio are examined, and the method to correct the response spectrum of ground surface considering the effect of excess pore water pressure is proposed. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
