Pollution characteristics of leachate and underground soul of the two landfill states were Investigated Domestic wastes were dumped In the two adjacent landfill states. Only small portion of S landifill site was filled with domestic wastes at the first stage of dumping, and most portion of the site was filled with construction wastes. However Y landfill strate was filed with mostly domestic wastes. Higher concentrations of organic pollutants including VOCs were measured In Y landfill site leachate than In S tendon site. Underground souls of the two linam states were analyzed by the two kinds of leaching methods, KEP (Korean Extraction Processl and Acid Digestion. Underground souls of the both landfill states were not polluted by leachates. Underground soils of the two were composed of firie salty material. Thus It Is fecund that fine silty soul layer of the sea shore may be used as a landfillsite.

Although landfill has been heavily relied upon as a final hazardous waste disposal method in Korea, the legal and technical problems associated with the landfill severely hinder proper disposal of hazardous wastes. The single largest legal problem is simply that, in spite of the recent amendments, the law regulating the hazardous waste landfill is yet in its primitive stage that even the lawful landfill sites cannot be regarded safe. The technical problems include improper selection of landfill sites, poor design and construction of landfill facilities, and lack of QA/AC and post-closure cares. These technical problems stem from inexperience and lack of resources. For the reduction of the potential danger from the improper landfills of hazardous wastes, it is an immediate need to further refine the law and to resolve the technical problems.

In order to analyze the movement characteristics of suspended solid(SS) in harbor construction, we investigate the generation and movement processes of the SS for the landfill construction by direct casting method and the grab dredging construction which is the most frequent process in harbor construction. We find that the SS is generated into a very high concentration right after the direct casting of landfill soil and continued up to 60 minutes in the landfill construction using the direct casting method with dredged materials by a ship of 700-tonnage. In the grab dredging construction, the SS is generated in a high density of concentration near at its source regardless of water depth, formed belt and diffused up to 700m along the trajectory of tidal current. Based on the result of the present study, it is recommended for the mitigation of SS generation that the silt protector be deployed near at construction site close enough to block the diffusion of SS and the body length of silt protector be long enough to mitigate the SS diffusion in the bottom layer.

The purposes of daily cover are to control odor and volatile organic compound emissions, to control litters, to mitigate rainfall infiltration. Under usual operation of landfill, the soil layer of 15cm thick is used for daily cover, but about $20{\sim}$25% of landfill capacity is consumed by daily cover volume. Considering our limited land and difficulty in getting landfill site, developing an alternative daily cover material which usually occupies much less volume than soil will be very significant. Also, if we can use waste material for alternative daily cover, we can get additional benefit of recycling waste.

With the shortage of the land and NIMBY syndrome, it is issued recently that the capacity of waste-landfill site is needed though the decreasing tendency of waste landfill. From this point, the stability is the most essential problem in the landfill that will be constructed. Advanced design and construction are most important for that. In this paper, for the study of desiccation, dry-shrinkage crack from drying and chemical reaction in cement hydration, which is occurred when the surface layer stabilization method is applied in wast landfill, laboratory test of the ground and specimen according to the mixture ratio of stabilizer is performed. From the result, it is notified that the uni-axial strength increases with the stabilizer, but dry-shrinkage increases too, therefore, it is important and the goal of this study to find the optimal mixture ratio of each stabilizer. Analysis of variance for regression with acting variables is performed to find optimal mixture ratio of each stabilizer.

To dispose of waste, there are methods such as landfill, incineration, recycling, and sea discharge. Since the landfill wastes accumulate, there is a limit to the landfill site to accommodate them. In this paper, a time series analysis and current status of landfill allowance was analyzed over 20 years of landfills distributed throughout the country using GIS to understand the status of waste reclamation. As a result, the emissions of waste were gradually increasing, and as the emissions increased, the amount of landfill increased. The landfills in the Seoul metropolitan area have been saturated and need to be resolved as soon as possible.

The DDC(dynamic deep compection) was carried out the main method of ground improvement for construction of municipal high way. The project area is composed of the municipal waste dumped, demolished building debris, coal ash and industrial waste made between 1983 and 1989. From the result of fileld measurement, it was found that waste landfill was compressed considerably (15 ~ 20% of full depth), and the strength was increased satisfactorily(20 ~ 120% of original N-value, 55 ~ 230% of original dynamic cone penetration resistance). And the chemical inclination of the municipal waste landfill was analyzed for expection and control of settlement.

In this paper, we constructed the systematic management and standardization of computerized landfill bringing system in Ansung landfill facility. During the system design process and database construction, we considered the specific items in Ansung landfill facility. And, we systemized and conventionalized the basic core data so as to we apply to another landfill facilities. And, we tried to standardize the system using the exception logic for specific items. For this purpose, we developed the landfill bringing management system which can help to manage a landfill efficiently. Basically We made efforts to standardize it's system architecture but also we considered it's localization to adapt An-sung Landfill's special requirements. We used RFID and LPR systems to distinguish a garbage truck from the others, and could establish more reliable landfill management system with this information. We expect that we can perform the systematic and the efficient landfill Bringing using the automated process of bringing in and taking out the waste process based on the developed system by automated RFID/LPR system.
