Long-term settlement analysis of the dump site of Marambaia, Nova Iguaçu, Rio de Janeiro, Brazil

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

This paper deals with the analysis of the compressibility of the old Marambaia dumping grounds’ MSW, located at Nova Iguaçu City (Rio de Janeiro) that was used as a waste dump from 1987 until 2003, when it was closed and remediated. The study was carried out based on superficial settlement monitoring data of reference points between 2008 and 2015. These data were analyzed considering the following compressibility models: Sowers, Meruelo, Ling et al. and Oweis. The results of the monitoring showed settlement values between 79 and 204 mm representing deformations in the range of 0.16 to 0.41% with regards to the of the landfill’s initial height. The models of Sowers, Merueloand Ling et al. render settlement values that are relatively close; revealing that, although being different in conception, both can be used to predict long-term settlements with a good approximation. The model of Oweis is the most elaborated of all models analyzed and predicted the greatest values for settlement.
