摘　　要：为研究V形双拱独塔斜拉桥各构件刚度对结构力学性能的影响,以西安沣河大桥为工程背景,采用数值分析法分析了V形双拱独塔斜拉桥主梁、拱塔、斜拉索及水平索等构件刚度对结构内力、变形的影响规律,并对各构件刚度的敏感性进行了对比分析.结果表明,各构件刚度对V形双拱独塔斜拉桥的力学性能均有相当程度的影响,其中主梁刚度对V形双拱独塔斜拉桥结构受力影响最大,斜拉索次之,而拱塔和水平索刚度对拱塔受力影响较大,对其他构件受力影响较小.For analyzing impact of stiffness parameter of structural member in cable stayed bridge with V shaped double arch single pylon, on the basis of the Fenghe River Bridge, numerical analysis method was used to analyze the influence of stiffness of the main girder, arch tower, cable stays, and horizontal cables on the internal force and deformation of the V shaped double arch single tower cable stayed bridge. The sensitivity of the rigidity of each component was compared and analyzed. The results show that the stiffness of each component has a significant influence on the mechanical properties of cable stayed bridge with V shaped double arch single pylon. Stiffness of the main beam has the most influence on cable stayed bridge with V shaped double arch single pylon, cable has the second influence, and arch tower and the horizontal cable stiffness have great influence on the force of the arch tower, and have less influence on other members.
