Laboratory testing of shear parameters through rock mass and along discontinuities: The Komarnica dam

Laboratorijsko ispitivanje parametara smicanja kroz stensku masu i po diskontinuitetima - brana 'Komarnica'

Abstract

  The paper shows the results of laboratory geo-mechanical tests of shear parameters (c - cohesion and ϕ - angle of internal friction) established on representative samples isolated at the site of construction of concrete arch dam Komarnica in Montenegro. For the testing of parameters of shear strength through rock mass, representative samples were used isolated from exploration wells. Testing of shear strength along fractures was made on cylindrical samples, which were isolated in exploration galleries. The paper shows test methods, analyses of results and concluding analysis. Tests on fractures were made at the Institute for the Development of Water Resources 'Jaroslav Černi' in Belgrade, and tests of shearing through mass at the Faculty of Mining and Geology in Belgrade.
