For the purpose of examining the characteristics of the aeolian sand in western Liaoning Province, this paper takes the aeolian sand as an experimental object to test the earthquake liquefaction properties. Based on the experiment data, the consolidation ratio, confining pressure, density and fine-grained content are analyzed to examine the influence rules of such factors to the anti-liquefaction strength and the different content on dry density and the fine-grained to the sand dynamic pore pressure development model is established.  Finally, the authors conclude that the factors such as density, fine-grained content and so on will have certain impact on the law of pore pressure increase.
