阐述了高强度螺栓摩擦连接的应用机理及摩擦系数对摩擦连接滑动承载能力的影响；指出钢材的强度及摩擦面的状态是影响摩擦系数值的两大因素；介绍了试件蕊板、复板厚度的确定及摩擦面的处理方法及工艺。
The mechanism of high strength bolt’s friction and the effects upon friction slip’s loading ability of friction ratio were elaborated. It is indicated that the steel’s intensity and friction surface’s state are two factors which affect the friction ratio. And methods of choosing sample of core board and cover board’s thickness, as well as the technology of friction surface were introduced.
