Abstract：In 2003, an MS6.8 earthquake occurred in Bachu-Jiashi region of Xinjiang, causing large-scale liquefied phenomenon. 44 in-situ Vs records are collected, including 19 liquefied survey points and 25 non-liquefied points. The shear-wave velocity of the in-situ records is verified using two typical liquefaction prediction methods, and all the success discrimination ratios are not satisfied. So a discrimination formula for soil liquefaction applicable to the Xinjiang region is proposed. This formula is based on the Chinese code for seismic design of buildings (GB50011—2010), which is a linear model. The formula is brief and convenient, while the evaluation success ratio of the liquefied sites is 84% and that of the non-liquefied sites is 84%, with the total discrimination success ratio being 84%. Based on the real data analysis, the proposed discrimination method is quite reliable, and it may provide technical support for liquefaction prediction in Xinjiang and the relevant regions.
