摘要
以某座双塔双索面三跨预应力混凝土梁与钢桁叠合梁斜拉桥为例,对影响双线铁路主跨280m叠合梁斜拉桥竖向刚度的各项因素进行了分析比较。
The paper takes a cable-stayed bridge with couple tower, couple cable, three-span prestressed concrete beam and steel truss composite beam for example, analyzes and compares various factors that affect the vertical rigidity of composite beam cable-stayed bridge of double line railway.
