摘要
桥型方案设计是桥梁设计的首要问题.新密市溱水路大桥桥型方案设计根据桥梁所处地理位置和作用,确定了桥型方案选择原则.对经济适用的60~100 m跨径的2跨桥梁结构进行研究,作出3种桥型方案进行对比分析.结合桥梁跨径不大、桥面较宽的特点,确定在国内首次将波形钢腹板箱梁应用于斜拉桥结构,为波形钢腹板箱梁组合结构在我国的推广应用作出新的尝试.
Bridge-style scheme design is a primary problem of bridge design.Based on the geographical location and its functions of the bridge,the principle was established in the bridge-style scheme design of the bridge on Zhenshui Road in Xinmi City.Three kinds of types were contrasted and analyzed after studying the economic bridge structure with two spans and the spanning from 60 m to 100 m.Combining with the characteristics of bridges with wide bridge floor and little big spanning,corrugated steel webs box girder was firstly used in cable-stayed bridge′s design,this makes a new attempt for popularizing and applying box girder with composition structures corrugated steel webs in our country.
