The forty original data of shear wave velocity in Handan area that had been collected were analyzed by using the quantile regression,the quantile regression models of two kinds of soil had been obtained by analyzing the changing law of shear wave velocity with depth increasing. The regression parameters and regression curve equation were obtained. The results show that the effect of depth to silt's shear wave velocity is unipolarity,and the effect of depth to silt's shear wave velocity show a trend of first increase and then decrease.
