| 摘 要： | 衢江大桥主桥采用V型刚构组合拱桥的设计方案,主跨主梁于拱脚处断开,并且采用体外预应力束作为系杆的方法来降低结构的墩底水平推力.针对该方案进行了内力分析,稳定分析和结构自振特性分析,为设计提供依据,研究结果表明这种方案是可行的.

| Abstract: | The V-frame composite steel pipe-concrete arch bridge plan is adopted in the plan design for QuJiang Bridge. The main beam of the main span breaks in the spring of arch, and external prestressed steel tendon as tie bar is used to lower the horizontal pushing force at the pier bottom. In this paper internal force analysis, buckling analysis, and mode analysis are done to provide reference for design. Research results indi cate this plan is viable. |

| Keywords: | V-rigid frame composite arch bridge tie horizontal pushing force |
