Field Application for Evaluating Vertical Stress of Soil in Multilayered Ground

In the west coast and the coast of Busan, at several locations, an overconsolidated layer exists above the soft ground. For soft ground with an upper overconsolidated clay layer, significant errors exist between the design and the actual settlements in the field. For multilayered ground, although Boussinesq's theory is applied, significant errors still exist. In this study, ground settlements in the overconsolidated clay layer were predicted using the Burmister and Hirai method. Based on comparisons with field measurements, it was confirmed that the accuracy could be increased by more than 90%.
