补充资料:组合体系桥
组合体系桥 combined-system bridge 主要承重构件采用两种独立结构体系组合而成的桥梁。如拱和梁的组合、梁和桁架的组合、悬索和梁的组合等。组合体系可以是静定结构,也可以是超静定结构。可以是无推力结构,也可以是有推力结构。结构构件可以用同一种材料,也可以用不同的材料制成。常用的结构形式有:①拱、梁组合体系桥。均为简单的拱梁组合体系有:单跨无推力结构,如系杆拱(即刚性拱和柔性拉杆的组合)、刚梁柔拱(又称郎格尔梁,为奥地利郎格尔所创始)、刚梁刚拱(又称洛泽梁,为德国H.洛泽所创始);较复杂的拱、梁组合体系为多跨布置的无推力或有推力的结构体系。如台湾关渡桥,为5孔连续中承式拱梁组合体系公路桥,主跨165米,1983年建成。②梁、桁架组合体系。桥面荷载直接作用在弦杆上,弦杆如同一个桁架节间长的实腹梁。③索、梁组合体系。如有加劲梁的悬索桥(如布鲁克林桥)和斜拉桥(如南浦大桥、杨浦大桥)均属此类体系。
