Utilizing Modern Rock Mechanical Model to Analyze the Derivation Tunnel of the Xigou Power Plant with ANSYS

The adjacent formation structure combined action model has carried out the finite element simulation analysis by using the ANSYS software as the platform utilization modern rock mechanical model between the west ditch hydroelectric power station derivation tunnel adjacent formation and the lining work function.The interface point is obtained through the computation results.It is very easy to be destructed,suggested or bound in the anchor rod reservation and concrete lining's steel bar welding when the same place,necessity increases some,simultaneously carries on the stabilizing grout to the adjacent formation.And the conclusion can be drawn through this project example.This law can be used in any tunnel to extract the adjacent formation and the support and protection structure stress and the displacement condition.
