Estudo da capacidade de carga de uma célula experimental de resíduos sólidos urbanos com base em ensaios de laboratório e campo

Abstract

In this research we study the geomechanical behavior of municipal solid waste from the Metropolitan West Caucaia landfill (ASMOC) where tests were performed on the soil surface and on residue of an experimental cell of municipal solid waste (MSW). Laboratory tests for the soil samples characterization consisted of granulometric analyzes, density, consistency indices, compaction Energy Standard Proctor and Index Support California (ISC) and for the characterization of solid waste in situ tests were performed like composition of gravimetric, moisture and specific weight. In field, tests were developed to determine the natural moisture content, through Speedy, natural specific weight through sand flask, standard penetration test (SPT) and plate load test.To evaluate the capacity of the MSW landfill, it was also held a standard penetration test (SPT) and plate load tests on a portion of the former landfill waste inside the ASMOC. It was settled yet superficial landmarks for the settlements monitoring in the experimental cell. After analyzing the results, we evaluated the future use of the study area for instance the foundation of small buildings, subgrade small access roads or green area of playgrounds. Based on the results, it can be stated that it is possible to use the MSW disposal area as support from foundations of small buildings, subgrade small access roads and green area of playgrounds, since biodegradation processes have been terminated, drainage systems of gas and leachate are rightly designed and that the soil surface is properly compacted.
