Two-dimension finite element analysis of the function of bolts supporting on layered rock tunnel
By use of ANSYS FEM software,under the circumstances of fixed tunnel height and changing span, a elastoplast ic two-dimension simulation analysis is conducted to the layered structure tunnel excavation, includ ing its stress, deformation and damage law.A different-depth tunnel rock deformation is discuss ed. The stress, deformation and damage laws of roof, floor and coal are acquired.
