Practicum of basic geomechanics 1300-OPGMP-GES
Introduction to Classes. Main conceptions.
Field tests. Indicator systems characteristic features of the rock mass (RQD, Q, GSI, JCR).
Preparation of specimens for testing purposes, quantifying of physical properties of rocks: volumetric density, porosity, absorbability, freeze resistance
Ultrasonic test.
Determining of mechanical properties of rocks. Strength tests in air-dry, water saturation state and after freeze cycles.
Indirect tensile and bending strength tests.
Geometric structure of contact surface and its influence on mechanical properties of rocks.
Failure criteria: Coulomb-Mohr failure criterion, Hoek'a-Brown failure criterion and generalized equation Hoek-Diederichs
Determination the rock mass parameters (mb, s i a), deformation modulus of the rock mass and the parameters of the Coulomb-Mohr (c, ) on the basis of the failure criterion Hoek-Brown.
Parametric analysis of changes in the distribution of stresses in the rock massive during excavation drill using boundary elements.
Determine the effect of the geometry of the tunnel on the stress distribution and visualization of the stress distribution around the mine.
Each course consists of a brief introductory lecture and practical exercises in the laboratory or in the computer lab.
Type of course
Learning outcomes
After completing the course the student has knowledge of the field and laboratory methods for testing the properties of rocks and rock massifs, and determines and interprets the results of strength tests.
Assessment criteria
Projects carried out in the classroom and computer lab, as well as the final oral exam.
One absence is allowed.
