The criteria for liquefaction judgment of fi ne-grained soil in current seismic design codes of China，the United States，and Bangladesh are quite different.In order to propose the judgment criteria for engineering application and Chinese code revision，this paper compared the judgment processes and criteria of the three countries.After analyzing the formation process，based on the application of the criteria for liquefaction judgment of 168 fine-grained soil samples collected in Dhaka，Bangladesh and surrounding cities，the rationality of each judgment process and criteria was evaluated comprehensively.Finally，a set of judgment processes and result criteria for fine-grained soil liquefaction integrating all criteria were put forward.
