跨海桥梁工程
bridge engineering of stride over a sea
kuahai qiooliang gongeheng跨海桥梁工程(bridgee嗯ineering of stride over a sea)跨越海峡或连接陆地与岛屿、海上建筑物之间的桥梁建筑工程。 跨海桥梁一般为多桥墩支承钢架式和少桥墩拉索式钢铁结构及钢筋混凝土结构。国外的跨海大桥多采用少桥墩拉索式钢铁吊桥，这是因为海洋环境恶劣、风浪海流都很大，不利于修建多个桥墩。跨海桥梁对于方便交通和开发海岛带来经济效益(参见彩图插页第80页)。 被称为世界20大奇迹之一的美国金门大吊桥，横跨金门海峡，像一条纽带把海峡连接起来，成了旧金山城的象征。日本连结本州到四国的岛际大桥—懒户大桥，由3条干线组成。其中西干线连接本州的尾道和四国的今治，长60千米，共建10座巨大桥梁;中间干线连接本州的小岛和四国的阪出，长37.5千米，中间横跨5个小岛，这条干线上的獭户大桥长1 100米，大桥的主梁高出海面65米;东干线长81千米，连接本州的神户和四国的鸣门，包括长1 629米的鸣门大桥和明石开镜吊桥。中国在1991年建成了厦门跨海大桥，由47对矩形桥墩撑起的大桥全长6 599米，宽23.5米，双向4车道。它是国内首次采用海上大直径嵌岩钻孔灌注桩施工法，滑移式钢模架设备和具有国际先进水平的预应力材料。1995年天津建成1 .2千米长的天津港南疆跨海大桥。(郑金林)
