ABSTRACT

In this study, very soft organic clay that causes many problems for embankment construction in deltaic areas was re-used as embankment fill material. Dewatering by evaporative drying, dewatering by horizontal sand drainage (clay-sand layers in a sandwich construction) and pre-loading (surcharging) were considered to be the most effective methods that can be applied for this type of soil. Artificial Neural Networks (ANN) and Genetic Algorithms can efficiently be used for this particular problem. By these means the use of very soft organic clay as a fill material for road embankment construction can be achieved in a safe and economic way. More data on such kind of construction would be an advantage in applying these models and methods in practice.
