The paper analyzes the influence of the shear slip and the bond disengaging to the stress and the bearing capacity of the steel tube arch,discusses the change law of the shear slip with the increasing of the axial pressure,describes the influence of the bond to the internal force distribution and the influence of the extrados disengaging to the local stress and the global stress,to accurately analyze the interaction of the steel pipe and the concrete.
