Potential of soil liquefaction at Perlis, Malaysia region

Abstract

Soil liquefaction is earthquake’s secondary effect which could cause fatal damages and structures instability. Despite Malaysia been located in stable zone of Pacific Ring of Fire, few significant surrounded quakes like Sumatra-Andaman earthquake had prompted Malaysian’s public concern, especially in Perlis area, on local seismic resistant. Hence, this Final Year Project report presents the analysis result of liquefaction potential of the soils, as the secondary effect of earthquake, within Perlis, Malaysia Region; the next strong and sustainable metropolis by using semi-empirical procedures introduced by Seed and Idriss. The study consists of two stages: (1) determination of the local geological and geotechnical site conditions within Perlis, Malaysia Region and (2) analysis of soil liquefaction susceptibility by using various methods and liquefaction potential by using Simplified Procedure developed by Seed and Idriss on stress approach. There are consist of four phases implemented in order to achieve the objectives targeted for the study after problem being identified. Firstly, a comprehensive review of literature on liquefaction at Perlis, Malaysia Region is carried out. Second phase is data collection process that includes collection of Site Investigation (SI) Report to represent from project PEMBINAAN DEWAN SERBAGUNA DAN LAIN-LAIN KERJA BERKAITAN DI DEWAN UNDANGAN NEGERI KUALA PERLIS, PERLIS, Malaysia Region. Thirdly, carry out data analysis utilizing suitable method. The final phase is to draw conclusions and recommendation on this study. It can be concluded the overall Perlis due to © This item is protected by original copyright vi earthquake moment magnitude below 7.5 has no potential to soil liquefaction. However, with the range of liquefaction potential of 1.6 to 5.64 in Kuala Perlis area is liquefiable. The developed liquefaction severity map of Perlis, Malaysia Regions, in particular the selected area, may be used by others as a reference for seismic design, standard safety measures as well as for further research work.
