Application of Grouting Intensity Number in Spillway Foundation at Jirau HPP/RO

February 24, 2020
Brazil has one of the largest hydroelectric parks in the world and important ventures for the world ranking have been executed in the country - to cite the most recent, Jirau and Belo Monte Hydraulic Power Plants (HPP). This emphasizes the importance in the continuous study of techniques and theories commonly used, in order to improve the quality of the projects...

Hydromechanical Behavior of Soil with Tire Fibers

April 22, 2020
Products derived from tires have been increasingly used for geotechnical engineering applications because of the economic, environmental, and social benefits they provide. The objective of this paper is to analyze the effect of the addition of rubber fibers from unserviceable tires on the hydromechanical behavior of argillaceous soil from the Barreiras Formation...

Bottom Reinforcement in Braced Excavations: Coupled Analysis and New Method for Basal-Heave Stability Study

May 26, 2020
Soil-cement bottom reinforcement is commonly used in braced excavations in soft soils, so that ground displacements can be reduced and excavation safety against bottom failure increase. However, there is a lack of studies in the literature regarding such reinforced excavations in which the stability against bottom heave is analysed through mechanical-hydraulic c...

Relationship Between Shear Wave Velocity and Piezocone Penetration Tests on the Brazilian Continental Margin

May 12, 2020

A detailed characterization of the shear wave velocity profile is an essential tool in the resolution of a variety of seismological and geotechnical engineering problems. The main objective of this study is to present equations capable of providing reliable shear wave velocity profile estimations based on CPTu parameters. The results of a series of pion...
