In view of these questions, this paper using soil dynamic double- parabola constitute model, which can consider the soil test damping ratio and can character main characteristic of soil’s hysteretic constituted relationship, associating with the highly effective explicit integral method with the high accuracy computation acceleration response, adopting global-local optimization technique, which uses genetic algorithm(GA)-simplex method, basing on MJ7.1 and the MJ8.0- two typical big earthquake records at TKCH07 borehole array in Japanese Kik-net network, the hysteretic nonlinear characteristic in time domain of the cohesive soil and the sand at TKCH07 borehole array are inversed and analyzed. The results indicated that, the modulus and the damping ratio of cohesive soil and the sand are basically consistent with the lab test results of Seed-Idriss and Kokusho. The mechanism and the history of hysteretic nonlinear constituted relationship under seismic strong motion are reproduced. The results reveal the permanent displacement mechanism. Simultaneously, velocity history and displacement history of ground strong motion are forecasted and estimated.
