Finite element numerical imitation research on beating open-cut tunnel
According to the fact that some tunnel entrances of the Wuguan expressway have to cross under the provincial road $201, and the upper part of the tunnel has to bear vehicles loads and interaction be- tween support and surrounding rock, using Ansys8.1 to establish finite element model and make numerical imitation calculation. Through calculation, the support structure and inverted arch as well as the joint site of inverted arch and bending wall stressed maximum. Then based on the calculation, modified distributed steel and cross-section size of sites which stressed much. The results of calculation and modification not only satisfied engineering needs but also to some extent have reference meaning to structure verification of bearing tunnel.
