Paper presented at the ISRM International Symposium, November 19–24, 2000
Paper Number: ISRM-IS-2000-587
... ABSTRACT: The paper presents the results of physical (geomechanical) model investigation of fractured rock behavior for validating the overall stability of openings excavated in the rock massif for a power house of a hydropower plant. Three types of tests were performed by geomechanical...

Paper presented at the ISRM International Symposium, August 30–September 2, 1989
Paper Number: ISRM-IS-1989-183
... ABSTRACT: The elements of the new theory of quantitative definition of fracturing, the estimation of structural hierarchy of rock massifs based on the spectral and correlation analysis of data of electrometric and nuclear-geophysical logging are set forth. The new method of the borehole...

... of the original natural stress state of the rock massif. As a result in different areas of the massif surrounding the structure a complex stress state arises, which is characterized by the Nadai-Lode parameter (Equation full in paper) Available experimental data show that in general the rheological...

Paper Number: ISRM-IS-1982-021
... SUMMARY: The state of stresses, both in the rock massif, surrounding a cavern and in the elements of a consolidating construction largely depends on the natural stresses, which have existed before the excavations, on the technology and the sequence of construction as well. It is suggested...

... system of equations is obtained. On the base of the so determined numerical values of the rheological parameters α ij and δ ij , by formulae (12), the rheological displacements at creeping at a given moment of the time and for an arbitrary point of the rock massif can be determined. Upstream Oil...

Paper presented at the ISRM International Symposium, October 23–24, 1973
Paper Number: ISRM-IS-1973-015
... Summary The increasing depths of open-pit mines require the solution of a number of slope stability problems. The considerable exposure of the highwalls, the influence of macro-defects in the rock massif, a considerable stress level here are some of the factors which cause...
