Abstract：The seismic subsidence of loess is greatly affected by the changes of water content and the corresponding influence is valuable for the evaluation and predication of the seismic subsidence of loess site. A series of dynamic triaxial tests of undisturbed loess under different water contents were carried out. The influence of water content on the seismic subsidence of loess was analysed and the evaluation and predication of the seismic subsidence of the sampled loess site were presented. The results showed that the coefficient of loess seismic subsidence increased with the increasing of the dynamic stresses or water contents. The critical dynamic stress of seismic subsidence decreased with the increasing of water contents. The seismic subsidence of loess with different physical properties was significantly different. For the loess site with water content no more than 5%，the seismic subsidence would generally not occur under the earthquake intensities of VII or VIII，while for that with the water content larger than 5%，the seismic subsidence would occur under earthquake intensity of VIII.
