PRIMJENA PARAMETARA STIŠLJIVOSTI U ANALIZI SLIJEGANJA KOMUNALNOG OTPADA

Abstract

In order to enable accurate modeling and numerical simulation of long-term behavior of the landfill, which is of great importance in the design of cover systems and closure of the waste disposal, it is necessary to know compressibility parameters. In contrast to the native soil, the main component of the overall settlement of waste is secondary compression. Therefore, the determination of the secondary compression index (Cα) or modified secondary compression index (Cα') is especially important. This paper presents some of laboratory results for municipal waste consolidation tests method as well as their role in settlement analysis of waste material. Sample tested was prepared artificially in line with the recommendations for sizes of the apparatus used and the largest particles in a sample (EN 1997-2, ASTM 2007a, 2007b). Different conventional models for prediction of municipal waste settlement were used settlement analysis was performed using the parameters of compressibility.
