Determinação do coeficiente de permeabilidade no aterro municipal de Toledo - PR

Abstract

The coefficient permeability of soil is an essential physical-hydraulic property for the design of septic tanks, water reuse and soil management techniques. Therefore, this work, it is presented an analysis of medium coefficient permeability of soil, at the Municipal Landfill of Toledo. For this, there were analysed the solo characteristics and its physics properties, as texture, density of grains, liquidity and plasticity limits. To determine such coefficient, it had been analyzed the results of infiltration tests, regulated by NBR 13969/1997, and the test of the concentric ring. There were established, yet, the interrelation between the permeability coefficients, according to the solo properties, as well as comparing the tests performances. After doing the tests analysis, it is verified that the prevalent grain size of the region is clay and the infiltration tests prove the low soil permeability. Finally, the results were satisfying, due to the low change between the values obtained.
