摘　　要：冷铸锚具、冷铸填料及其灌注固化、超张拉力等是影响斜拉索分丝板内缩值的主要因素,通过对上述因素进行有效控制,大规格斜拉索分丝板内缩值也能满足国标GB/T18365—2001不大于6mm的要求。The chill cast anchor socket, filler of the socket, solidifying of the filler and excessive stressing of the wires are the principal factors influencing the withdrawal values of the wire divider plates of stay cables. By way of effective control of the aforesaid factors, even the withdrawal value of a large size wire divider plate can meet the requirement for withdrawal value less than 6 mm as specified in the Chinese National Standard GB/T 18365-2001.
