ANISOTROPíA MECáNICA DEL NEIS DE LA CASA DE MáQUINAS DE LA HIDROELéCTRICA PORCE III

in this work is presented the results of the different laboratory tests carried out on gneissic intact rock of the porce iii hydroelectric project, colombia, in order to determine the degree of deformation and failure strength anisotropy under stress. this study concludes that the gneiss is a sound, brittle, of high strength and low grade anisotropic rock, and can be well modeled by a transverse isotropic linear elastic behavior under the drucker-prager failure criterion.
