Abstract: The liquefaction potential of a construction site has significant impact of the optimization design and the capital investment. This paper presents a state of the art review of the liquefaction evaluation of a site. The code method and simplified Seed method are used to evaluate the same site. The results indicate that a higher liquefaction potential evaluated by the code approach in higher fine content in silty soils, compared with the Simplified Seed method.

Key words: Liquefaction Evaluation, Code Method, Simplified Seed Method
