Back analysis method of elastoplastic BEM in strain space
Abstract
In this paper the back analysis of elastoplastic BEM is presented on the basis of the plastic theory in strain space. The method can be applied to back analysis of underground cavity. And the initial stresses in rock mass and Young’s modulus can be calculated from the displacements measured along the side of cavity. In the paper the approximate middle-point stiffness method to solve non-linear equations is proposed, with which convergence can be obtained more quickly.
