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...

Rockburst From Floors

December 13, 2018

The purpose of this work is the calculation of the optimal parameters involved with advanced drilling of gas-draining holes. These holes are made to floor entryways and provide an efficiency test for floor degas extractions, like the AB bed at the Uralkali’s Berizniki Ore Development Unit No 2 and Unit No 4 (Mine 2 and Mine 4). Current conditi...

An Alternative Method to Estimate the Effective Energy During Pile Driving Based on Set and Elastic Rebound Records

June 02, 2019

Although the dynamic load test technique has been developed for a long time, it became very popular in Brazil over the last 20 years (especially after the publication of Brazilian Standard NBR6122, in 2010). However, the site quality control of driven piles in respect to the resistant capacities remains with the practical application of the so-called &a...

Soil Classification System from Cone Penetration Test Data Applying Distance-Based Machine Learning Algorithms

July 08, 2019
Most work from the literature dedicated to soil classification systems from cone penetration test (CPT) data are based on simple two-dimensional charts. One alternative approach is using machine learning (ML) to produce new soil classification systems or to reproduce existing ones. The available studies within this research field can be considered limited, once ...
