A research is made to investigate the drainage efficiency of horizontally placed draining layers in soils with sand drains by using the average degree of consolidation to scale the drainage efficiency.The research showed that it is feasible to use fly ash and other industrial wastes as the medium of radial drainage layer in hydraulic fill to obtain ideal drainage result
