Obtaining the Mechanical Parameters for the Hardening Soil Model of Tropical Soils in the City of Brasília

April 04, 2019
In this article, the mechanical parameters of characteristic soils of the city of Brasília are obtained, calibrated and validated for the Hardening Soil (HS) model, based on laboratory and field test results obtained in previous research studies conducted in the Experimental Field of the University of Brasília (CEGUnB). The strength and compressibi...

Dynamic Cone Penetrometer (DCP) Relative Density Correlations for Sands

May 14, 2019

The dynamic cone penetrometer (DCP) is a widely used in-situ device to determine the engineering properties of soils. This paper reports a meta-analysis of laboratory calibration studies to establish a relationship between the rate of penetration and relative density for sands. Fourteen (14) different sands from different geographic and geological setti...

Geotechnical Behavior and Soil-Fiber Interaction of Clayey Soil Mixed with Randomly Dispersed Coconut Fibers

July 08, 2019
This study aims to experimentally analyze the influence of the addition of different amounts of short coconut fibers on the geotechnical properties of tropical clay soil. Samples with 0, 0.5, 1, and 2 wt% of fiber in regard to the dry weight of soil were analyzed. Compaction, direct shear, compressibility, hydraulic conductivity, scanning electron microscopy (SE...

Behavior of Geosynthetic-Encased Stone Columns in Soft Clay: Numerical and Analytical Evaluations

October 24, 2018
The type of improvement technique that will be applied to a soil beneath an embankment depends on the nature of the problematic soil existing at the site. Soft soils beneath embankments typically present high compressibilities and low shear strengths. In some cases, geosynthetic-encased stone columns (GECs) have shown advantages over other solutions to improve e...
