金门大桥

金门大桥是世界著名大桥之一,被誉为近代桥梁工程的一项奇迹, 也被认为是旧金山的象征。(金门大桥不愿 金门大桥及旧金山夜 景说明的是,这个伟大的建筑奇迹同时又被认为是全球首选的自 杀圣地)。金门大桥的设计者是工程师史特劳斯,人们把他的铜 像安放在桥畔,用以纪念他对美国作出的贡献。大桥雄峙于美国 加利福尼亚州宽1900多米的金门海峡之上。金门海峡为旧金山海 湾入口处,两岸陡峻,航道水深,为1579年英国探险家弗朗西 斯·德雷克发现,并由他命名。 金门大桥的北端连接北加利福尼亚,南端连接旧金山半岛。当船 只驶进旧金山,从甲板上举目远望,首先映入眼帘的就是大桥的 巨形钢塔。钢塔耸立在大桥南北两侧,高342米,其中高出水面 部分为227米,相当于一座70层高的建筑物。塔的顶端用两根直 径各为92.7厘米、重2.45万吨的钢缆相连,钢缆中点下垂,几乎 接近桥身,钢缆和桥身之间用一根根细钢绳连接起来。钢缆两端 伸延到岸上锚定于岩石中。

金门大桥包括从钢塔两端延伸出去的部分,全长达2000米, 为此,又分别在两侧修建了两座辅助钢塔,使桥形更加壮观。 大桥的桥面宽27.4米,有6条车行道和两条宽敞的人行道。 当船只驶进旧金山,从甲板上举目远望,首先映入眼帘的就 是大桥的巨形钢塔。钢塔耸立在大桥南北两侧,高342米, 其中高出水面部分为227米,相当于一座70层高的建筑物。 塔的顶端用两根直径各为92.7厘米、重2.45万吨的钢缆相连, 钢缆中点下垂,几乎接近桥身,钢缆和桥身之间用一根根细 钢绳连接起来。钢缆两端伸延到岸上锚定于岩石中。大桥桥 体凭借桥两侧两根钢缆所产生的巨大拉力高悬在半空之中。 钢塔之间的大桥跨度达1280米,为世界所建大桥中罕见的 单孔长跨距大吊桥之一。从海面到桥中心部的高度约60米, 又宽又高,所以即使涨潮时,大型船只也能畅通无阻。

金门大桥是世界著名大桥之一,被 誉为近代桥梁工程的一项奇迹,也 被认为是旧金山的象征。 金门大桥的设计者是工程师史特劳 斯,人们把他的铜像安放在桥畔, 用以纪念他对美国作出的贡献。大 桥雄峙于美国加利福尼亚州宽1900 多米的金门海峡之上。金门海峡为 旧金山海湾入口处,两岸陡峻,航 道水深,为1579年英国探险家弗朗 西斯·德雷克发现,并由他命名。

悬 索 桥 的 优 缺 点



优点 相对于其它桥梁结构悬索桥可以使用比较少的物质来 跨越比较长的距离。悬索桥可以造得比较高,容许船 在下面通过,在造桥时没有必要在桥中心建立暂时的 桥墩,因此悬索桥可以在比较深的或比较急的水流上 建造。 悬索桥比较灵活,因此它适合大风和地震区的需要, 比较稳定的桥在这些地区必须更加坚固和沉重。 缺点 悬索桥的坚固性不强,在大风情况下交通必须暂时被 中断 悬索桥不宜作为重型铁路桥梁 悬索桥的塔架对地面施加非常大的力,因此假如地面 本身比较软的话,塔架的地基必须非常大和相当昂贵。 悬索桥的悬索锈蚀后不容易更换。金门大桥悬 索 桥 的 结 构

悬索桥,又名吊桥(suspension bridge)指的是以 通过索塔悬挂并锚固于两岸(或桥两端)的缆索 (或钢链)作为上部结构主要承重构件的桥梁。其 缆索几何形状由力的平衡条件决定,一般接近抛物 线。从缆索垂下许多吊杆,把桥面吊住,在桥面和 吊杆之间常设置加劲梁,同缆索形成组合体系,以 减小活载所引起的挠度变形。 按照桥面系的刚度大小,悬索桥可分为柔性悬索桥 和刚性悬索桥。柔性悬索桥的桥面系一般不设加劲 梁,因而刚度较小,在车辆荷载作用下,桥面将随 悬索形状的改变而产生S形的变形,对行车不利,但 它的构造简单,一般用作临时性桥梁。刚性悬索桥 的桥面用加劲梁加强,刚度较大。加劲梁能同桥梁 整体结构承受竖向荷载。除以上形式外,为增强悬 索桥刚度,还可采用双链式悬索桥和斜吊杆式悬索 桥等形式,但构造较复杂。

金门大桥于1933年动工,1937年5月竣工,用了4年时间和 10万多吨钢材,耗资达3550万美元。整个大桥造型宏伟壮 观、朴素无华。桥身呈朱红色,横卧于碧海白浪之上,华 灯初放,如巨龙凌空,使旧金山市的夜空景色更加壮丽。

一八六九年,美国“皇帝”诺顿一世下令在 旧金山海湾建一座悬索桥,此后又几次下诏 命令建桥.和他的其他圣旨不同的是,这道圣旨 最终不仅被奉行,并且归功于他,只不过迟了六 十多年,一九三三年,旧金山开始在诺顿一世 规划的地址建悬索桥,一九三六年,这座世 界上最著名的大桥之——金门大桥建成,在 它的一根桥梁上挂牌纪念诺顿一世"旅行者, 请停步并感谢美国皇帝和墨西哥保护者诺顿 一世(一八五九至一八八零在位)他有先见之明, 构想并下令在旧金山海湾建桥"。

这项工程的造价约为400万到500万美元。当地的环保 部门还要对工程进行进一步审查,确保其不会对环境 造成破坏,也不会影响到金门大桥的美观。虽然给大 桥围网的初衷是好的,但此计划还是招致了一些异议。 批评人士指出,与其在大桥上一掷千金,还不如用这 笔钱来帮助自寻短见者战胜心理疾病,提高他们的心 理健康水平,这样才能从根本上解决问题。
由于桥面到海面的距离长达60米,再辅以人坠落时巨大的 冲击力,自杀者基本上没有生存的可能性。仅2009年一年 就有39人在这里跳桥身亡,2008年的自杀人数则为19人。 居高不下的自杀人数使旧金山相关部门头痛不已。其实早 在20世纪70年代,就有人提议在大桥上装上特定设施以阻 止人们跳桥。当地桥梁管理部门于2008年10月10日投票决 定在大桥上安装不锈钢网,这样整座大桥都会被网“兜” 起来,自杀者就不会直接坠落到海面了。

金门大桥 Golden Gate Bridge

金门大桥  Golden Gate Bridge

金门大桥Golden Gate Bridge(旧金山)The orange towers of the Golden Gate Bridge-probably the most beautiful, certainly the most photographed bridge in the world-are visible from almost every point of elevation in San Francisco. The only cleft in Northern California's 600-mile continental wall, for years this mile-wide strait was considered unbridgeable. As much an architectural as an engineering feat, the Golden Gate took only 52 months to design and build, and was opened in 1937. Designed by Joseph Strauss, it was the first really massive suspension bridge, with a span of 4200ft, and until 1959 ranked as the world's longest. It connects the city at its northwesterly point on the peninsula to Marin County and Northern California, rendering the hitherto essential ferry crossing redundant, and was designed to withstand winds of up to a hundred miles an hour and to swing as much as 27ft. Handsome on a clear day, the bridge takes on an eerie quality when the thick white fogs pour in and hide it almost completely.Y ou can either drive or walk across. The drive is the more thrilling of the two options as you race under the bridge's towers, but the half-hour walk across it really gives you time to take in its enormous size and absorb the views of the city behind you and the headlands of Northern California straight ahead. Pause at the midway point and consider the seven or so suicides a month who choose this spot, 260ft up, as their jumping-off spot. Monitors of such events speculate that victims always face the city before they leap. In 1995, when the suicide toll from the bridge had reached almost 1000, police kept the figures quiet to avoid a rush of would-be suicides going for the dubious distinction of being the thousandth person to leap.Perhaps the best-loved symbol of San Francisco, in 1987 the Golden Gate proved an auspicious place for a sunrise party when crowds gathered to celebrate its fiftieth anniversary. Some quarter of a million people turned up (a third of the city's entire population); the winds were strong and the huge numbers caused the bridge to buckle, but fortunately not to break.泰姬陵泰姬陵Taj Mahal介绍英文版The construction of this marble masterpiece is credited to the Mughal emperor Shah Jahan who erected this mausoleum in memory of his beloved wife,Arjumarid Bano Begum;popularly known as Mumtaz Mahal,who died in A.H. 1040 (A.D. 1630)。
