Design of a New Computer Code: Modification and Substantiation of a New Methodology in Determination and Analysis of Site Liquefaction Potential

Liquefaction is a process in which a soil suddenly loses its strength and most commonly occurs as a result of ground shaking during a large earthquake or other rapid loading. The aim of this study is providing and developing of a geotechnical- based computer code for nonlinear site response analysis, employing the field and laboratory tests and also combination of several softwares, represents a new method for evaluating the liquefaction potential. In order to verify the proposed method, the Avaj-Changureh earthquake of 2002 was applied on Korzan earth dam in Hamedan province and for determination of its accuracy; it was compared with several known techniques. The obtained results showed proper compatibility with other known methods.
