Geocomat를 활용한 폐기물매립장의 사면안정성 검토

In this study, slope stability analysis of LCRS(Leachate Collection Removel System) in waste landfill was performed by large scale field test. Geocomat is new type of geocomposite product. Gecomat is a sort of geocomposite product. It is composed of nonwoven geotextiles, woven geotextile, and geonet. Large scale field tests were performed on the slope of different two LCRS sections with static loading condition. One is LCRS section which consisted of GCL, HDPE and Geocomat. The other one is GCL, HDPE, and woven type geocomposite. The behavior of geosynthetics lined slope(1:1) was monitored by incorporating instrumentation including vertical soil pressuremeter, settlement plate, strain gauges, potential meter, displacement pin. Based on the field monitoring result, magnitude of sliding on the Geocomat LCRS section is much less than that of sliding on the conventional geocomposite LCRS section.
