Abstract

Single-stage construction technique and multi-staged construction technique are two embankment-construction techniques that are generally used on soft soils. A single-stage construction technique is usually used for fast construction of comparatively low-height embankments. A multi-staged construction technique is mostly used for construction of high embankments. In this study, the PLAXIS software is used to conduct a 2-D finite element analysis that evaluates the influence of sequential construction of embankments. Data from a Lebuhraya Pantai Timur2 highway project in Malaysia were investigated. For every phase of embankment construction, the stress concentration ratio, the safety factor, and the overall and differential settlement have been estimated. According to the results of this study, using the stage construction technique improves the shear strength of the soil, which was evaluated in terms of the measured settlement. On the other hand, the sequence construction analysis reveals a vaguely different safety factor and stress concentration ratio against the stability observed in the results derived through the non-sequential construction technique. Lastly, the objective of the study is to provide sufficient information on the behaviour of a multi-stage construction procedure of an embankment carried out over a soft clay soil and strengthened by stone columns.
