A proper geotechnical site characterization has to identify the geometry of relatively homogeneous zones and define indices, strength and stiffness properties of the soils within these zones. The most widely used in situ test to define the stratigraphical profile and to estimate geotechnical parameters is the Standard Penetration Test (SPT). Although it is widel...

This paper advances understanding of the key parameters controlling unconfined compressive strength (qu) of lime stabilized fine-grained soils by considering distinct specimen porosities (η), different lime types and contents and several curing temperatures and time periods. A sole empirical relationsh...

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...

This 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 ...
