Abstract

The Sigli - Banda Aceh Toll Road passes through an area where the subgrade consists of soft soil. Geotechnical issues usually arise that settlement over a relatively extended period, which can damage the structure constructed above it. One of the improvement methods for soft soil problems is a Prefabricated Vertical Drain. The result of consolidation settlement takes a very long time, 21.7 years. Therefore, soil improvement is required beforehand using the Preloading method in combination with Prefabricated Vertical Drain. A prefabricated vertical drain will be paired up to a depth of 8 meters. The installation pattern used is a triangular pattern from 1 meter, 1.25 meters, 1.5 meters, 1.75 meters, and 2 meters. Based on analytical calculations, it can be concluded that the embankment construction process must be carried out step by step, and the construction speed is limited and using installation distance of 1 meter requires 57 days, an installation distance of 1.25 meters requires 80 days, an installation distance of 1.5 meters requires 118 days, an installation distance of 1.75 meters requires 160 days, and an installation distance of 2 meters requires 211 days to achieve a consolidation degree of 90 percent. So, a greater installation distance.
