The results indicate that the parameter identification method for rock-fill material proposed in this article is accurate, has a fast convergence rate and can be applied in practical engineering applications.
The examples described above point to great potentialities of the geophysical methods for rock deformation monitoring.
Centrifugation technique is among various methods for rock capillary pressure measurement.
This study has also clearly shown the limits of presently available strength estimation methods for rock masses and further work is required to develop more precise, practical, and easy-to-use methods for determining the rock mass strength.
Amaefule et al. (1993) introduced FZI and RQI methods for rock typing and thereafter these methods have been used widely in the literature (Gunter et al. 1997; Porras and Campos 2001; Jennings Jr and Lucia 2003; Rincones et al. 2000; Soto et al. 2001).
The selection of efficient support methods for rock tunneling is a key factor in order to reduce the number of problems during construction and maintain the project cost and time within the limited budget and planned schedule.
Direct standard testing method for measuring rock brittleness, the combination of rock properties rather than only one rock parameter have not available yet.
We present a method for predicting rock types.
