Quantitative Assessment of the Disturbance Factor in Hoek–Brown Formulas
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.
