补充资料:梁桥
| 梁桥 beam bridge 以受弯为主的主梁作为承重构件的桥梁。主梁可以是实腹梁或桁架梁。实腹梁构造简单,制造、架设和维修均较方便,广泛用于中、小跨度桥梁,但在材料利用上不够经济。桁架梁的杆件承受轴向力,材料能充分利用,自重较轻,跨越能力大,多用于建造大跨度桥梁。按照主梁的静力体系,分为简支梁桥、连续梁桥和悬臂梁桥。①简支梁桥。主梁以孔为单元,两端设有支座,是静定结构。一般适用于中、小跨度,结构简单,制造、运输和架设均甚方便,多做成标准设计,以便于构件生产工艺工业化、施工机械化,提高质量,降低造价。如洛阳黄河桥(67孔跨径50米,全长3429米,1977年建成)。郑州黄河桥(28孔跨径20米、62孔跨径50米、47孔跨径40米,全长5550米,1986年建成)、开封黄河桥(31孔跨径20米、77孔跨径50米,全长4475米,1989年建成)均为公路预应力混凝土T形简支梁桥。②连续梁桥。主梁若干孔为一联,连续支承在几个支座上,是超静定结构。当跨度较大时,采用连续梁较省材料,更适合用悬臂拼装或悬臂灌筑、纵向拖拉或顶推法施工。如京石公路永定河桥,为预应力混凝土箱形连续梁,1988年建成;武汉长江桥、南京长江桥为钢桁架连续梁桥。③悬臂梁桥。上部结构由锚固孔、悬臂和悬挂孔组成,悬挂孔支承在悬臂上,用铰相联。有单悬臂梁桥(三跨构成,中跨较大以满足通航要求)和双悬臂梁桥(可构成多跨的长大梁桥)。如陕西省咸阳渭河桥(主跨174米,全长448米,1954年建成)为钢筋混凝土悬臂梁桥。梁桥为桥梁的基本体系之一,使用广泛,在桥梁建筑中占有很大比例,其上部结构可以是木结构、钢结构、钢筋混凝土结构、预应力混凝土结构或钢筋混凝土桥面板和钢梁的组合结构。
