Feasibility of liquefaction prediction method in China's seismic code to Xinjiang region

Ms6.8 Bachu-Jiashi earthquake of Xinjiang causes a large scale of soil liquefaction, which has shown the most notable phenomenon of sand liquefaction in China since Tangshan Great Earthquake in 1976. In terms of the investigations and field tests in the Bachu-Jiashi liquefied areas in 2009, the feasibility of the liquefaction evaluation method in China's code for seismic design of buildings is discussed. The results reveal the successful judgment ratio by the code is 85% for non-liquefied sites and is only 43% for liquefied sites in Bachu area of Xinjiang. The code will lead obviously risky judgments and isn't suitable for Bachu area in deed. The data for the method in China's seismic code are mainly from Tangshan, Tonghai and Haicheng Earthquakes in China, furthermore the conditions of Bachu-Jiashi area are quite different from the data of the code, therefore, an appropriate local method for liquefaction prediction in Xinjiang region should be established.
