Deformation Characteristics of Lime Stabilized Marine Clay Using Finite Element Method

Abstract

The coastal area is one of the environmentally vulnerable areas, with soil characteristics such as weak soil and marine clay, which is classified as hazardous soft soil. Because marine clay has poor mechanical and physical properties, foundation conditions such as pad footing were unstable and prone to corruption. As a result, the lime column will be used to stabilize marine clay in this study. The purpose of this research is to investigate the deformation of marine clay with lime to increase shear strength and reduce excessive settlement by analyzing data from previous studies and conducting a review of the literature, as well as to investigate the deformation of untreated and treated marine clay with lime columns and PLAXIS software projection. Compared to the traditional method, PLAXIS 2D software is one of the most cost-effective ways to test a foundation, such as the pad footing. At the same time, PLAXIS 2D was able to shorten the time required to achieve an analytical result. The results of the settlement and stress value have been taken after the computation and analysis from PLAXIS 2D. The greatest percentage difference between untreated and treated marine clay for stress and displacement is 81.82 percent and 7.98 percent, respectively.
