This paper presents investigations on the behavior of four types of rocks (syenite, granite, marble and sandstone) subjected to abrasive waterjet cutting. The influence of traverse velocity and pump pressure on the efficiency of cutting is analyzed. Moreover, the influence of the physical-mechanical behavior of the rocks on their removal process is inve...
View ArticleThis research aims to describe how rainfall can cause changes in the piezometric pore pressure and soil matric suction in a densely instrumented slope by the South BR-101 (Brazilian Numbered Highway), in the area of Morro do Boi, in the State of Santa Catarina, South Region of Brazil. The slope presented a history of instability movements instigated by ...
View ArticleConsidering the increasing incidence of cyclic loadings on engineering structures and the enhancement of design analysis, soil testing under cyclic conditions has renewed its importance. Laboratory tests are conducted to simulate as near as possible field conditions. Assumed conditions aid on the choice of the tests to be conducted in order to determina...
View ArticleThe Standard Penetration Test (SPT) is often used to estimate the soil parameters for geotechnical design projects, using the NSPT index. However, these estimates are performed based on empirical correlations without any scientific basis. Moreover, the test has a large inherent results dispersion due to the us...
