Abstract

Abstract

Based on joint load test of lining segment, the change regularity of the different factors influencing the bending stiffness of a longitudinal joint was studied, and then the calculation formula for the bending stiffness of longitudinal joint was deduced. The results indicate that the different factors have great effect on the bending stiffness of longitudinal joint when the axial force is relatively small, and they have limited effect on the bending stiffness of longitudinal joint when the axial force is up to a certain level relatively great. The joints structure has a significant influence on the bending stiffness of longitudinal joint.
