Resumo: | ||||||||
Rock masses are submitted to biaxial and triaxial states of
stress. Deformability and strength properties of rocks
under such conditions are essential data for calculating
bearing capacity of foundations, design of dams, mining
excavations, oil exploration, tunnelling etc. For these
purposes, laboratory and in situ tests are of great
importance. Studying rock behaviour when submitted to
triaxial loading is of great concern, due to the difficulty
in carrying out biaxial tests and because triaxial state of
stress is more common. This thesis presents the design and
construction of a triaxial cell for laboratory tests
in rocks, which is able to support a confining pressure as
high as 70 MPa. The equipment allows internal specimen
instrumentation. Top and bottom pore-pressure measurements
have been predicted, and fluid percolation through the
specimen is possible. Tests on steel and rock specimens
were carried out to comission the equipment. The rock
tested is a leptinite gneiss found in the city of Rio de
Janeiro (Morro Dona Marta).
