摘要
城市高架道路和立交工程中常见的门式墩,通常在墩顶设置多支点横梁。结合上海中环线浦东段(上中路越江隧道—申江路)工程,介绍了不同支点数和不同横向跨径的横梁在不同布载形式的作用下,计算结果的归类比较,同时分析了多支点预应力混凝土横梁的受力性能和特点,可以为该类结构的优化设计提供借鉴。
The gantry piers are common used for urban elevated bridge and intersection project,above which there are the cross beam with multiple supports.Taking the Mid-ring(Shangzhong Rd.Tunnel-Shenjiang Rd.) project in Pudong for example,the prestressed concrete cross beams with multiple supports and different spans are analyzed through the comparison of different calculated results between different types of distributed load.The result could provide valuable technical information and idea for the optimization design of the similar structure.
