Abstract

This paper presents an implementation of numerical analysis using pressure dependent hyperbolic model to estimate liquefaction potential on sandy layers in University of Bengkulu’s sites. Two sites located at the embankment area and the swamp area are studied. Furthermore, non-linear one-dimensional seismic response analysis is performed to investigate the soil behaviours, such as the excess pore pressure, the hysteresis loop, and effective stress path. In this study, the ground motion of Elcentro is used as the input motion at the base of investigated sites. In general, this study could recommend the practical analytical method in seismic response analysis to consider the liquefaction effect before constructing. The results show that the investigated sites are vulnerable to undergo liquefaction, especially for layers dominated by loose to medium sandy soils. It can be therefore concluded if a strong earthquake with the peak ground acceleration similar with the input motion happens near the location, the liquefaction damage will be possible to occur.
