Environmentally friendly foundation for the sustainability development of infrastructures in swamp area

摘要

Infrastructure development in Indonesia,especially,has moved into swamp areas.Swamps are usually associated with saturated clay and peat soils that are soft and highly compressible.The low bearing capacity and the high excessive settlement are usually solved with piles and pre-consolidation.The remove and replace method with new and better material is sometimes also used.Those methods have really changed the characteristics of the soils and are not friendly to the environment.Some foundation constructions for soft soils have also been proposed,but,in their application,there are technical constraints which are difficult to overcome.Research on the light foundation in soft soils has been carried out to support the light load with a satisfactory settlement.Further studies are carried out to obtain a foundation construction that can support larger loads,but which are still friendly to the swamp environment.The bearing capacity and settlement of foundation is plotted in the graph to formulate the satisfaction indicators of the foundation.In addition,the simple formulation procedures for practical application requirements will be also provided since it is the target of this research for general applications.This foundation is very useful for the sustainability of infrastructure developments that is environmentally friendly.
