Discussion for Quality Appraisal of Layered Rock-mass
Song Yan-hui · Journal of Yangtze River Scientific Research Institute · 2005
On the basis of the engineering practice of the rock-mass quality classification of certain power station in southwest China, and in combination with the universal methods used at home and abroad, some major factors influencing rock-mass quality of layered rock-mass such as original bedding, soft interlayer and dip angle of the rock stratum are expounded. The problems occurred in the process of appraisement, such as the aeolotropism of the layered rock-mass, spring feature of evaluating indicator and the influence of the layered structure on evaluation results etc., are analyzed. Some problems needed to be noted on layered rock-mass quality appraisal are put forwards.
