摘　　要：以某大桥为背景,介绍了矮塔斜拉桥施工控制的原则和目标.结合钢绞线斜拉索的自身特点,介绍了钢绞线斜拉索的张拉方法,根据矮塔斜拉桥结构的特点,提出以控制主梁上下缘应力的原则,索力一次张拉到位的控制方法,使斜拉索索力和主梁线形均达到了设计要求.Based on the construction of an extradosed cable-stayed bridge,this article introduces the principles and objectives of the construction control of the extradosed cable-stayed bridge and the tension method of strand stayed-cable according to its own characteristics.In light with the structure characteristics of the extradosed cable-stayed bridge,it also proposes the principles to control the lower and upper stress of the main beam and the control method that the cable force is strained one time to get the ideal force so that both the cable force and the bridge linearism can reach the requirements of design.

关 键 词：施工控制 矮塔斜拉桥 钢绞线拉索 等张力法 索力
