摘　　要：分析了剪切滑移和粘结脱空两种类型的作用对钢管拱受力及承载力方面的影响,论述了随着轴向压力增大的剪切滑移效应的变化规律,阐述了粘结对内力分配的影响及拱背脱空对钢管拱局部及整体受力的影响,从而较准确地分析了钢管与混凝土之间的相互作用问题。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.
