Abstract

The 6.5 Mw Aceh earthquake has been struck the north-east part of Sumatra Island on 7
December 2016. The strong quake was at a depth of 13 km and categorized as a shallow earthquake. The
earthquake has caused many damages to the roads as results of lateral spreading in Pidie Jaya Regency. This
study is conducted to analyze the liquefaction phenomena that caused lateral spreading on the Pidie Jaya
roads. All of the soil data for the analysis were taken from the field of the affected area. First, the soil data are
analyzed to examine whether the soil sediment has the potential to liquefaction under the earthquake. Then
the detailed analysis to observe the phenomenon of liquefaction on a particular road embankment is
conducted with the use of numerical computer program. This study shows that for particular soil sediment
which has liquefaction potential, the structure stability analyses need to consider liquefaction circumstance at
a certain level. Finally, a reasonable geo-construction analysis is suggested for preventive measures of
liquefaction.
