GEOGRID REINFORCED SOIL STRUCTURES TO INCREASE LANDFILL CAPACITY

摘要

Two geogrid reinforced soil structures have recently been used to successfully increase the capacity of a waste landfill in Hong Kong. A geogrid reinforced soil wall and a geogrid reinforced soil embankment have been constructed on the perimeter of the landfill to substantially increase the void space for waste. This paper summarises the design of the reinforced soil structures, the selection and quality control of the geogrids and fill material, and the facing details to prevent the outside face of the embankment structure being damaged during a possible hillside grass fire.
