摘要
以泉州金屿大桥为研究实例,根据公路和轨道所处位置及作用,提出平层、双层和分离3大形式,6种共建设计模式。分别从交通组织、桥梁结构和受力、施工、经济性等几个方面进行多方案比较分析,最终选择平层轨道居中的设计模式,其具有平纵线型协调、交通组织顺畅、设计简洁、施工方便、经济性好等优点。
Taken Jinyu bridge in Quanzhou city as an example,six design models generated from three major forms of flat,double and separation layers are proposed according to the bridge position and the function of highway and railway. The flat layer and middle-orbit designing pattern is finally selected by comparing the character of traffic organization,bridge structure and force,construction and cost respectively. There are several advantages for the selection： more harmony in vertical and horizontal coordination,more efficient in traffic organization,easier in site practice,more convenient in construction and more economic in cost.
