摘　　要：斜拉桥销铰连接锚固系统由斜拉桥锚头、销铰连接件、锚固耳板、夹板及高强螺栓组等组成,传力途径为斜拉索—销铰连接件—锚固耳板—钢箱梁腹板—钢箱梁,销铰连接件与斜拉索锚头间通过螺母承压传力,连接件与锚固耳板间通过销轴连接,锚固耳板与钢箱梁腹板通过高强螺栓组连接。锚固耳板与销轴间可转动,以适应活载及温度作用下的转动变位。锚固耳板与钢箱梁腹板间通过摩擦力将斜拉索力传至钢箱梁。舟山桃夭门大桥目前在国内首次采用这种连接方式。The pinhinge connection anchorage system of the cablestayed bridge consists of the anchorage head, the pinhinge connection, the anchorage plate, the holding plate and the hyperstrong bolt and nut. The load is transmitted through the cablepinhinge connectionanchorage platesteel box beam bottom platethe steel box beam. The load is transmitted through the nut between the pinhinge connection and the cable anchorage head. The connection and the anchorage plate are connected by a pinaxle. The anchorage plate and the steel box beam bottom plate are connected by the hyper strong bolt and nut set. The plate and the pinaxle can rotate against each other so as to adapt to the live rotation under the action of the live loading and temperature. The load from the cable is transmitted to the steel box beam by friction between the anchorage plate and the bottom plate. This connection is used for the first time on Zhoushan Taoyaomen Bridge.
