摘要
乐都县城西大桥为 6× 2 0m后张法预应力混凝土空心板梁桥 ,下部为四柱四桩式结构 ,桥面总宽 2 6 .5m ,设计荷载为城A级。设计中对上部结构空心板梁作了进一步优化 ,节约了材料用量 ,缩短了工期 ,收到了良好的经济效益 。
Ledu Bridge is a post tensioned prestressed concrete hollow slab beam bridge with 6×20m. The substructure is a four column and four pile type structure. The total width of the bridge is 26.5m and the design loading is Chen A class. In the design the hollow slab beam of the superstructure is further optimized so as to save the material consumption, shorten the working stage and get a good economical effect. The paper introduces the optimum design of the hollow slab beam.
