The shear strength of rock masses

The first section of this thesis describes the creation and analysis of a database on concrete and masonry dam incidents known as CONGDATA. The aim was to carry out as complete a study of concrete and masonry dam incidents as practicable, with a greater emphasis on the geology, mode of failure, and the warning signs that were observed. This can be used in initial risk assessments of large concrete and masonry dams along with analysis of stability for various annual exceedance probability f1ood. It was found that failure through the foundation was common in the list of dams analysed and that information on how to assess the strength of the foundations of dams on rock masses was limited. This thesis uses case studies and databases of intact rock and rockfill triaxial tests collated by the author to review the current Hoek-Brown criterion. The results highlight the inability of the criterion to fit all types of intact rock and poor quality rock masses. New equations were derived for estimating the shear strength of intact rock and rockfi1l.
