摘　　要：针对矮塔混凝土斜拉桥结构受力特点,依据影响矩阵调值原理,应用MIDAS/CIVIL2010"未知荷载系数"模块,对常熟常浒河混凝土矮塔斜拉桥工程进行了成桥索力优化。分析结果表明,该方法可以方便地得到满足设计要求的合理成桥索力,且便于施工过程索力优化与结构内力的控制。In response to the bearing features of low-pylon concrete cable-stayed bridges, on the basis of the influence matrix principles,using the ＂Unknown load factor＂module in MIDAS/CIVIL2010,the finished cable tension state of Changhu river low-pylon concrete cable-stayed bridge was optimized. The results show that the reasonable cable tension of finished state which meet design requirements can be easily got by this method.
