Assessment of liquefaction-induced settlement of piles exceeding the specified settlement at the area of Anutapura Medical Center in Palu, Indonesia

Liquefaction-induced settlement, which can severely damage infrastructure and structures in earthquake-prone areas, is a major concern. To decrease the effects of liquefaction-induced settling, pile foundations are typically used to transfer loads to deeper and more stable layers of soil. To assess the liquefaction-induced settlement of piles at a specific location in this study, the interaction among seismic, soil, piles, and structures will be taken into consideration. The shape, composition, and soil conditions are all considered in the analysis of how the piles behave under seismic loading. The liquefaction-induced settlement is assessed using a comprehensive numerical modeling approach. The soil, piling, and structures are modeled using SAP2000, and the seismic loading is predicted using information from prior earthquakes. The dynamic soil-structure interaction is taken into account in the model in order to account for the nonlinear behavior of the soil and piles during liquefaction. The analysis clarifies the potential for liquefaction to cause piles to settle beyond the predetermined settlement. It considers elements including the depth of the water table, the thickness of the soil layer that is liquefiable, and the particulars of the anticipated earthquake. The assessment’s findings show that although the construction site is vulnerable to liquefaction, damage from the liquefaction-induced settlement is unlikely.
