摘　　要：针对桥梁支座更换问题,结合具体的工程实例来阐述钢抱箍法的设计合理性,首先应用高强螺栓连接三块圆弧钢板,通过钢抱箍紧箍在墩柱上产生的摩擦力提供上部结构的支承反力,然后对高强螺栓数量、抱箍体应力以及加劲肋的强度进行验算以完成钢抱箍设计。Aiming at bridge bearing replacement,this paper discussed the rationality of the steel hoop design combining with concrete engineering examples. Based on the three arc steel plates connected by high-strength bolts,the friction on the pillar by steel hoop provided support load of super structure. The number of high-strength bolts,stress of steel hoops and the strength of stiffening rib were calculated.

关 键 词：高强螺栓 钢抱箍 支承反力 加劲肋
