以青田塔山大桥为例,采用参数分析的方法,探讨了基础刚度、V形墩倾角、墩身尺寸、合拢顶推力等结构设计参数对V形墩连续刚构桥整体受力性能的影响,最后得出了参数变化时结构内力状态的变化规律. 研究结论表明V形墩倾角是最重要的设计参数,对主梁和墩柱的受力性能有着很大影响;基础刚度、墩身尺寸、合拢顶推力对上部结构主梁受力性能影响相对较小,对墩柱受力性能影响相对较大.

Taking Qingtian Tashan Bridge as an example, the influence of structure design parameters on me-chanical behavior of continuous rigid-frame bridge were discussed in detail with the method of parameter analy-sis.These parameters contained the foundation stiffness, the dip of V-shaped pier, size of V-shaped pier, the closure jacking force, and so on.At last, the change rules of structural mechanical behavior with the change of structure design parameters were given.Research results showed that the dip of V-shaped pier was the most important design parameter, which had great influence on bending moment of girder and piers.Other parameters such as foundation stiffness, sizes of V-shaped pier, closure jacking force had less influence on mechanical behavior of girder, but they had certain influence on mechanical behavior of V-shaped piers.
