Abstract

In this paper, conventional triaxial compression tests were conducted to obtain the full stress-strain curve of deep roadway rock mass. Considering the post-peak flow and drop failure of the curve, the surrounding rock was divided into three zones: elastic zone e+ plastic flow zone w+ fracture zone b. Subsequently, the constant total load assumption was introduced, and the closed-form analytical solutions for stress, strain, displacement, and radius of each zone in surrounding rock were derived based on this assumption. The results are equivalent to the corresponding results based on conventional stress boundary conditions; moreover, applying this theory to the calculation and analysis of engineering examples shows that the results are basically consistent with the actual situation. The research results can provide references for the study of roadway surrounding rock deformation.
