桥梁

Ab stract : Continuous slabΟdeck is an important structural measure for simplyΟsupported girder bridge , but it is easy to be damaged and difficult to be repaired which is a common problem of simple supported beam highway bridge.

桥面连续构造是简支桥梁的一个重要构造措施，但很容易损坏，且易损难修，是公路简支桥梁的通病。

Suspensorily joined structure has the virtue that the construction progress is normally fast and does not hinder the traffic underbridge because Travelling Carriage is not used,but requiring comparatively large construction plant, high complexity in seam assembling, lower structural integrity compared to the suspensorilyplaced are its faults.

预应力混凝土T型刚构加挂梁结构是公路桥梁常用的一种桥梁结构型式，这种桥型根据施工方法的不同可分为悬浇和悬拼，悬浇结构需采用挂篮施工，优点是结构无干接缝，整体性好，刚度大，施工占用场地少，缺点是施工期间挂篮将影响桥下的通航通车，施工周期长；悬拼结构的优点是无需采用挂篮施工施工进度快，对桥下的通航通车影响较小，缺点是需占用较大的施工预制场地，拼装接缝处理难度大，结构整体性较悬浇差。

Interstate 80 bridge over State Street in Salt Lake City is very near the Wasatch fault, which is active and capable of producing large earthquakes.

发展的桥梁抗震加固规范与碳纤维增强复合材料复合材料摘要：美国80号州际公路桥梁多国街在盐湖城犹他非常靠近断层，这是积极的，会产生大地震的能力。

In recent decade, with the rapid development of transportation enterprise, many long-span bridges have been constructed or constructing, for deceasing load and increasing the span, the orthotropic steel deck is generally applied for the long-span steel bridge.

近十年来随着交通事业的快速发展，已建成或正在建设的大跨径桥梁逐渐增多，为了减小桥梁自重和增大跨径，大多数钢桥的桥面板一般采用正交异性钢桥面板。

Because operating rigid frame bridges have chief diseases at present. A diseasing bridge is evaluated by using analytic hierarchy process and expert evaluation combined factor method at first, then the reinforcement measure is studied based on evaluation consequence, the calculation of internal force and deformation are carried Out by the finite element method, and the evaluation analysis of reinforcement effect is done by calculation result.

针对目前正在运营的刚架混凝土拱桥出现的主要病害，首先利用基于层次分析及专家评估的变权综合系数法对一实际病害桥梁结构进行了评估，然后根据评估结果对该桥的维修加固措施进行了研究；采用有限元方法对桥梁加固后的内力和变形进行了计算，并根据计算结果对该桥的加固效果进行了评估分析。

It was there, in fact, that the three bridges disgorged upon the right bank, and bridges lead to the building of houses rather than palaces.

实际上，新城通往右岸的三座桥梁便是从这里开始的。总是桥梁先产生民宅，然后才产生王宫的。

The bridge is a hymn, it eulogizes the science strength, the technique is being ingenious and the work honor; The bridge is a genre painting, it is the national character and style, the historical vicissitude modern drama stage.

桥梁是赞美诗，它讴歌着科学的力量，技艺的巧妙和劳动的光荣；桥梁是风俗画，它是民族风情、历史变迁的话剧舞台。

Thus, this plan schems out four years research period, employs value simulation analysis tool, keeps the thorough understanding of the damage mechanism of the subjected to debris flow indued loads.

鉴於此，本计画拟订四年研究期间，透过数值模拟分析工具，深入了解桥墩受土石流冲击破坏机制，进而提出未来强化结构设计及加劲材料选用等桥梁主体改善对策，据以作为未来交通主管单位设计山区跨河桥梁时之参考。

With the progress of technology and the development of bridge construction, there mushroomed a whole variety of skill-advanced bridge projects.

随着科技的进步和桥梁建设事业的发展，各种技术先进的桥梁工程纷纷涌现。

Do not attempt to drive across bridges or overpasses that have been damaged.

不要试图穿越已经损坏的桥梁。*地震停止后小心前进，注意道路和桥梁的损坏情况。

I will endeavour to find you some assistance.
