<![CDATA[One of the bridge construction projects in Kalimantan was built on soft soil using a piled embankment reinforcement system. The reinforcement used is a combination of minipile and geotextile poles. However, after the landfill was carried out on the bridge embankment, a settlement is occured of approximately 0.6 m in a period of 3 months. Studies are conducted to evaluate and review the causes of decline. In addition, optimization of the design was carried out in this study. Evaluation is carried out by reviewing the bearing capacity of single and group piles of the minipile based on Standart Penetration Tests data. The calculation of load distribution on piled embankments follows the regulation of BS 8006. Deformation analysis is performed with Plaxis 2D program. Based on the analysis results, it was found that the ultimate bearing capacity of the pile group under the embankment was not able to withstand the working load. The settlement that occurred in the bridge's oprit was most likely caused by the collapse of the soil. Based on the consolidation analysis using plaxis, a value of 0.6 m was obtained within 90 days. Based on the evaluation results, the optimization of the design was carried out using the same method, namely using a pile embankment but differed in the dimensions and installation configuration. The design optimization results show that the bearing capacity is sufficient and the resulting average total deformation is 0.0435 m.]]>
