Nonlinear analysis of rock with weak structural planes by BEM |
| |
Abstract: | The weak structural planes modeled as Goodman joint elements and a Mohr Coulomb criterion for shear strength, also a nonlinear analysis method is suggested. For the multiregion problem ,a efficient block equation solver is used so that the large practical problem can solved by micro computer. |
