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 ...

Investigating the Differences between Various Deterministic Liquefaction Correlation Methods

May 24, 2019
In order to manage the risks associated with an earthquake, a particular attention should be given to reduce and resist the effects caused by the earthquake such as soil liquefaction. Several evaluation procedures have evolved over the last four decades, since the use of the simplified method suggested by Seed & Idriss in 1971. However, these procedures pres...

Geological-Geotechnical Characterization of Slopes Belonging to the Serra do Mar Paranaense, Brazil

July 08, 2019
An extensive campaign of field and laboratory tests were performed on samples of residual soils and colluviums present in the morphoscultural sub-unit comprising Serra do Mar Paranaense located in Southern Brazil. The geotechnical investigations included the physical characterization, in situ hydraulic conductivity and the mechanical behavior of the soils, by me...
