补充资料:拱桥
拱桥 arch bridge 以承受轴向压力为主的拱圈或拱肋作为主要承重构件的桥梁,拱结构由拱圈(拱肋)及其支座组成。拱桥可用砖、石、混凝土等抗压性能良好的材料建造;大跨度拱桥则用钢筋混凝土或钢材建造,以承受发生的力矩。按拱圈的静力体系分为无铰拱、双铰拱、三铰拱。前二者为超静定结构,后者为静定结构。无铰拱的拱圈两端固结于桥台,结构最为刚劲,变形小,比有铰拱经济,结构简单,施工方便,是普遍采用的形式,但修建无铰拱桥要求有坚实的地基基础。双铰拱是在拱圈两端设置可转动的铰支承,结构虽不如无铰拱刚劲,但可减弱桥台位移等因素的不利影响,在地基条件较差和不宜修建无铰拱的地方,可采用双铰拱桥。三铰拱则是在双铰拱的拱顶再增设一铰,结构的刚度更差些,拱顶铰的构造和维护也较复杂,一般不宜作主拱圈。拱桥按结构形式可分为板拱、肋拱、双曲拱、箱形拱、桁架拱。拱桥为桥梁基本体系之一,一直是大跨径桥梁的主要形式。拱桥建筑历史悠久,20世纪得到迅速发展,50年代以前达到全盛时期。古今中外名桥(如赵州桥、卢沟桥、悉尼港桥、克尔克桥等)遍布各地,在桥梁建筑中占有重要地位,不仅适用于大、中、小跨径的公路桥和铁路桥,因其造型优美,更常用于城市及风景区的桥梁建筑。
