Analysis of tough clay soil plastic index from several quarries in Aceh Besar District for seismic mitigation

Abstract

Abstract Clay soils that tend to have the potential for landslides and earthquake-induced cracking are a serious problem in the development of infrastructure and settlements in the area. This research investigation sample was collected at a quarry in several areas of Aceh Besar District to identify problematic soil behavior in various quarries. The method used was stabilization by conducting compaction testing to obtain the optimum moisture content of the natural soil. The quarry soil samples taken were disturbed samples, which were then tested directly at the Soil Mechanics Laboratory. The data used in this study is the plastic index (PI) value. This research aims to assess stabilization strategies for problematic clay soils as an earthquake risk mitigation effort in the Aceh Besar region. The results of this study are expected to provide practical guidance for stakeholders in planning and developing more earthquake-resistant infrastructure in Aceh Besar. The result of the test showed that the OMC value was 36.3% with a dry weight of 1.22 gr/cm3.
