Bearing Capacity and Settlement Behavior of Peat Soil Improve by Stone Column

Abstract

The stone column is the standard ground improvement method used on the peat soil but, there are no clear guidelines to use the stone column, so this study will be conducted to achieve the objective. This study aims to model the stone column in the peat soil by using the PLAXIS Software to determine the peat soil's bearing capacity and settlement and compare the bearing capacity and settlement with various stone columns; geometry, and properties. By using the PLAXIS 2D Software, to model the stone column and the peat soil in order to analyse the behavior of the peat soil with different geometry of the stone column. In this study, the bearing capacity and settlement have been determined and the results of bearing capacity and settlement with different geometry of stone column have been compared. Hence, suitable geometry of stone column can be applied and became common options of ground improvement techniques besides preloading and vertical drains (PVD).
