Abstract
By employing the effective variance of stress tensors as a scalar-valued measure of stress heterogeneity, we quantitatively analyse the influence of boundary constraint stiffness on numerically derived stress distribution in a fractured rock mass. The results reveal a decreasing trend in the effective variance of stress field with an increasing boundary constraint stiffness. This work demonstrates the efficacy of effective variance for stress heterogeneity quantification, and also indicates that the boundary constraint stiffness can affect stress modelling results. We suggest that quantitative evaluation of the effects of boundary constraints may be needed in geomechanical modelling of fractured rock masses.
