| 摘 要： | 洞诺融江大桥是广西三江至柳州高速公路的重要工程之一。文章通过对洞诺融江大桥的桥型进行多方案设计,对预应力混凝土连续刚构桥和独塔双索面预应力混凝土矮塔斜拉桥这两个桥型方案进行综合比较,最后采用了施工工艺成熟、造价低及后期养护简单、费用较少的主桥70＋125＋70m预应力混凝土连续刚构方案。

| Abstract: | Dongnuo Rongjiang Bridge is one of the most important projects in Sanjiang to Liuzhou highway.Through multiple plan design on bridge type and comparison between pre-stress concrete continuous rigid bridge and a single pylon and double cable plane pres-tressed concrete extradosed cable-stayed bridge,the 70＋125＋70 m pre-stress concrete continuous rigid bridge plan was selected because it has a mature construction technique,lower cost and is easy to maintenance. |
