Geogrid Mechanical Damage Caused by Recycled Construction and Demolition Waste (RCDW): Influence of Grain Size Distribution

April 06, 2020
Recent studies have shown that recycled construction and demolition waste (RCDW) can be used as backfill material in geosynthetics reinforced soil (GRS) structures. However, besides the environmental and economic benefits of this practice, it is necessary to evaluate the mechanical damages that RCDW could cause to the reinforcement elements. This study aims to i...

Residual Shear Strength of a Residual Soil of Granulite

February 14, 2020

This paper discusses the residual shear strength of a granulite residual soil that was involved in a large landslide in Brazil. The residual strength was investigated because of the great mobility achieved by the soil after failure. The experimental program comprised physical and mineralogical characterization and residual shear strength measurements. D...

Numerical Investigations on Seismic Bearing Capacity of Interfering Strip Footings

April 30, 2020
The interaction between footings placed at close proximity affects the ultimate bearing capacity, settlement, and tilt of adjacent footings, especially under seismic loading. This paper reports the numerical finite element analysis to investigate the interference effect on the seismic bearing capacity of closely spaced rigid strip footings for a wide range of fo...

Effects of Hydraulic Gradient Variation on the Structure and Strength of a Compacted Tropical Soil

May 26, 2020
Tropical soils have been extensively studied to evaluate the technical feasibility of their application in hydraulic earthworks such as compacted clay barriers in landfills. In these earthworks, the water flow in the porous medium generates percolation forces that can promote structural changes in the soil, with possible deleterious repercussions on its mechanic...
