Conventional fictitious stress methods (FSM) employ numerical integration to calculate displacements or stresses on each element unit. The paper represents a kind of three-dimensional fictitious stress method adopting analytical integrals over triangular leaf elements instead of numerical integration and describes how to analyze stress and displacement of surrounding rock around roadway by the 3D-FSM. The results computed by this method were compared with the results obtained by Flac3d, which proved that it is a correct and rational method to solve three-dimensional mechanics problems especially about hole and crack in an elastic body.
