A method based on the application of Kötter’s equation is proposed for the complete analysis of passive earth
pressure on a vertical wall retaining horizontal cohesionless backfill. The unique failure surface consisting of log spiral and
its tangent is identified on the basis of force equilibrium conditions. On...
This technical note presents some preliminary results obtained with the use of hydrophobic and hydrophilic
tensiometers to measure liquid pressures in three-phase systems (air-NAPL-water). The porous tips of the hydrophobic
tensiometers underwent a surface treatment known as silanization. The silanized tensiometers demonstrated l...
This work studied the transport phenomena in the soil of the Gramacho MSW landfill located in Rio de Janeiro,
Brazil. A model was proposed to determine the mass transfer rate of the leachate contaminant ions to the soil particles.
Previous researchers have focused on the diffusion and sorption phenomena using simple relations tha...
It is commonly accepted that the shear strength of Municipal Solid Waste (MSW) is enhanced by the
reinforcement effect of its fibrous constituents. However, most papers in the technical literature do not systematically
evaluate the effect of the MSW fibers on its stress-strain-strength response. This paper presents results of a s...
