Abstract

In Indonesia, a region frequently affected by earthquakes, ensuring the seismic safety of building structures is critically important. This safety consideration must extend beyond the superstructure to include the substructure as well. One significant threat to the substructure is the risk of soil liquefaction, which can markedly reduce the bearing capacity of the soil during an earthquake. This research employs a quantitative approach, involving direct field soil exploration and sampling. The collected soil data is used to assess the soil’s susceptibility to liquefaction. At the study site, it was determined that the predominant soil type is loose sand, coupled with a high groundwater table. This combination indicates a potential for liquefaction from depths of 1.5 meters to 13 meters. The research model encompasses two groups of piles, both of which demonstrate a reduction in axial bearing capacity by 79%.
