| Abstract: | Combined with benching construction （temporary transverse support） at the entrance of Baitushan Tunnel. the displacement of the surroundina rock and the mechanical properties of the support structure in such construction at the large-section tunnel entrance are simulated with finite element numerical analysis. Through the analysis on the calculating results, the safety and rationality of this method is recognized offering basis for the design and implementation. |
