Through standard penetration test, cone penetration test and macro discriminating method, the liquefaction potential of silty soil of a project in Handan is evaluated, and the results are analyzed comparatively. According to the factors and characteristics considered in discriminating method, combining the regional characteristic of silty soil, the synthetic discriminating method, which is suit to the saturated silty soil in Handan, is put forword, thus improves the dependability of evaluation of liquefaction potential.
