The Settlement Ratio Prediction of Compressible Soil In Area Under Embankment

Abstract

This paper aims to predicting the ratio of settlement under the toe embankment, outer side of embankment and the centre of embankment. The methods used in this study are the empirical approach to estimate the index compression value (Cc) for compressible clay soil. The magnitude of soil subgrade settlement is carried out using a 1-dimensional compression formula developed by Terzaghi and considers the soil subgrade is an over consolidated clay. This study uses several variables such as the embankment dimension by considering the height and width of embankment and the depth of compressible layer of soil subgrade. Those variable uses to compare the ratio of settlement depend on those variables. The results obtained from this study are the settlement ratio of toe/centre is around 0.23 and the settlement ratio of outside/centre is around 0.84. The empirical formulation of settlement ratio for various condition are described in this study.
