The Research and Application on Calculation Model of the Stagger-Jointed Assemble Lining Structure
A new calculation model of stagger-joint assemble is presented. The model can reflect three ways to transfer shear force between adjacent rings. To simplify the calculation model, a friction shear contact element is coded on ABAQUS secondary development platform and the nut of bolt is embedded in the segment. Using the model to analysis the Tunnel Through Yellow River, the results show that the integral rigidity of the lining structure improve obviously and the local modify effective have an impact on the adjacent area near ring-joint surface more than away from area.
