Rock Mechanical Parameters

In-situ testing of rock mechanical parameters is essential for rock mass characterisation. The rock mass characterisation is important in design and construction of underground works forming major component of Hydropower projects. The major civil structures of most of the hydropower projects planned in Nepal have to be founded on complex rock formations on fragile geological environments. In-situ rock mechanics tests carried out at various hydropower projects sites are described and the findings are summarised.

The paper describes the results of making the mathematical and physical models of the authors, by using analogous methods and materials. There is the mathematical rock mass deformability model as a base for foundation engineering a concrete arch dam and the physical rock slope model which was tested by loading until failure and the results were compared with the calculation procedure. In the first example the correlation is established between the static and the analogous dynamic in situ investigations for creating the mathematical rock mass deformability model. In the second example there is application of the analogous materials for the discontinuity shearing simulation on the physical slope model. The results of the geotechnical in situ investigations and laboratory testing carried out in the Institute for Development of Water Resources "Jaroslav Cerni" in Belgrade were used for making the models.

Disturbance Factor

Due to the subjectivity and limitation for estimating the disturbance factor in the Hoek–Brown formulas, this paper proposes the term "the generalized disturbance factor" and points out that this term is more appropriate in describing the degree of disturbance of the Hoek–Brown rock mass. The longitudinal wave velocity is selected to quantify the generalized disturbance factor. The feasibility of the recommended method is examined in this paper by use of the basic data and in-situ testing results of a project.

ABSTRACTThe geological disposal of radioactive waste, based on a multi-barrier concept wherein the first barrier consists of the metal waste container and the final barrier the host rock, is widely considered the only viable solution.Following disposal the risk will remain of the formation of gases due to corrosion and other processes. Research being carried out at the Czech Technical University in Prague (CTU), Centre of Experimental Geotechnics (CEG), the Josef underground laboratory as part of FORGE and other projects focuses on gas migration in underground areas and especially within the EDZ.The research consists of several stages including the design of gas conductivity equipment destined for in-situ testing and the gas conductivity tests proper. An important part of the research involves the evaluation of a potential correlation between rock mass classification parameters and gas conductivity; a certain degree of correlation was identified in earlier research projects. The discovery of such a correlation would greatly assist in the future design of underground gas storage and deep radioactive waste facilities.
