摘　　要：本文以某下承式钢管混凝土系杆拱桥为背景,针对施工过程中吊索张拉力计算这一关键问题。结合该桥施工步骤,采用倒拆法和影响矩阵法相结合的方法,计算出了该拱桥吊索施工张拉力,并在实桥中得以应用,取得了比较好的效果。Based on a concrete filled steel tubular arch bridge,this paper pays close attention to the tensile force of the suspenders during construction.According to the bridge construction process,the tensile force of the suspenders is calculated by using the negative sequence method and influence matrix method,and the calculation result has been applied in the real bridge.

关 键 词：钢管混凝土拱桥 吊索张拉力 倒拆法 影响矩阵法
