Abstract

The fictitious stress method (FSM) based on analytical integral of Kelvin’s solutions to calculate displacements or stresses have been proposed by K.Kuriyama. The paper represents the procedure how to use this method to compute stresses and displacements of rocks underground, and a modeling method for tunnel and bolt drilling element. In additional, some roadway with one prestressed bolting is taken as example and plot the Szz component of stress compared with Flac3d result. The FSM which employs integral of Kelvin’s solution as influence coefficients is a calculation method of high accuracy, and the computation time complexity is lower compared with either the finite element method or finite difference method.
