Geotechnical properties of Brazilian weak sedimentary rocks
(2014-01-01)
The sedimentary rocks cover about 70% of the Brazilian territory. Large sedimentary basins, from the Paleozoic to the early Cenozoic, present a wide variability of lithology, raging from coarse grained rocks as the ...
Water-Rock Interactions in the Bauru Aquifer System - Sao Paulo State, Brazil
(Elsevier B.V., 2017-01-01)
The study focuses on the assessment of mineral saturation indexes using data of physicochemical analysis of groundwater samples from different units of the Bauru Aquifer System, in the State of Sao Paulo, Brazil. The ...
The role of asymmetries in rock-paper-scissors biodiversity models.
(Águas de Lindóia, 2014-01-29)
The maintenance of biodiversity is a long standing puzzle in ecology. It is a classical result that if the interactions of the species in an ecosystem are chosen in a random way, then complex ecosystems can't sustain ...
Sensitivity analysis of hydraulic properties of naturally fractured reservoirs
(2020-01-01)
This work aims to apply a sensitivity analysis to determine the influence of natural fractures in a cross section of rock reservoir cell, assessing the equivalent permeability of the medium. Using finite elements with high ...
Laboratory simulation of the disintegration of clayey rocks of the Corumbatai Formation (Rio Claro, Brazil)
(A A Balkema Publishers, 1998-01-01)
THE GEOTECHNICAL BEHAVIOR OF BRAZILIAN SEDIMENTARY-ROCKS
(A A Balkema, 1993-01-01)
Numerical modeling of evolving discontinuities in rocks using solid interface finite elements
(2019-01-01)
This work presents a numerical technique capable of handling evolving fractures in rocks that allows extending, in a simple manner, standard finite element programs developed for geological (continuum) media to deal with ...
Determination of rock fracture toughness under creep and fatigue
(1995-01-01)
The paper describes the results of stable servo-controlled Brazilian compression tests on granite. The tests have been successfully used for the determination of rock fracture toughness. In the tests described here, after ...
General Report for TC102 In-Situ Testing
(Presses Des Ponts, 2013-01-01)
An overview of all the technical papers accepted for the in-situ testing session of the 18th ICSMGE is presented. Forty two papers submitted to this conference were considered as part of this session. The papers were grouped ...
