Assessment of Liquefaction Potential Using Optimum Seeking Method

Abstract

The use of the cone penetration test (CPT) resistance data as an index for liquefaction assessments is receiving increased attention because of the advantages of this in-situ test method. This paper investigates the feasibility of using the optimum seeking method to assess liquefaction potential from actual CPT field data. Optimization theory is a very important branch of applied mathematics, and has a wide application in the practical world. Using the available field liquefaction and nonliquefaction data, the influence of various factors is quantified using the optimum seeking method. The factors considered are: the earthquake magnitude,
