Abstract/Summary

Abstract. Liquefaction accompanied by strong earthquake ground shaking is destructive to the built environment. If such is not studied and prevented then more lives and properties will be lost.

An evaluation tool efficient in analyzing and evaluating liquefaction potential in a fast and easy way is developed. The evaluation tool for liquefaction potential is capable of identifying the liquefied and non-liquefied zones in a particular area. And for further appreciation, a graphical representation of the liquefied and non-liquefied zones is shown to visualize the output.

The general method adapted is based on the empirical relationship between the standard penetration resistance and the cyclic stress ratio causing liquefaction developed by Seed and colleagues (Seed and Idriss, 1971). However, their works (formulas and equations) have been updated and reviewed (NCEER, 1996) and thus used in the project study.

The borehole data such as the depth of the water table, depth of soil, type of soil, SPT N-value and total weight of soil and the earthquake data such as the earthquake magnitude and maximum acceleration are the input values. The software performs all other necessary computations ending with the factor of safety. The factor of safety is the most important criterion in determining whether the area will liquefy or not.
