Abstract
Coastal final disposal sites are planned and constructed for two purposes : the proper disposal of wastes and, once disposal is fully completed, utilization of sites vacant properties for port and/or urban development projects. There are, however, some discriminative characteristics associated with coastal final disposal sites. For example, in comparison to inland landfills, stabilization of the disposed waste takes longer at coastal sites and it is also necessary to manage and control the residual water levels in the allowable range, etc. Due to problems such as these, research and development on these technologies, for more effective utilization of the sites, must be implemented.
From this point of view, our work has categorized the acceptance criteria for operating coastal final disposal sites, evaluated the geotechnical characteristics of the waste landfill layer and evaluated the effects of improving the strength of the soil layer using a mixture of iron slag (a co-product of the iron industry).
