When making design with bridge configuration, bridge deck overlay which was only treated as the appendant of bridge, currently not make special calculate and analyze about it, at the same time, current codes also just give directed account for method、material and thickness of deck pavements, there havent any design theory and index to dependent, so it is necessary to do some systemic study about concrete bridge deck overlay and make certain about the stress and distortion characteristic of the deck pavements.

桥面铺装作为特殊的路面结构，它起着保护桥梁和承担路面功能的作用。但是目前，在进行桥梁结构设计时，桥面铺装层只是作为桥梁工程的附属结构，一般不作专门的计算分析，现行规范也只是对桥面铺装的做法、材料、厚度做了指导性的说明，至今没有可以依据的设计理论和指标，因此有必要对桥面铺装展开系统的研究，明确铺装层结构的受力和变形特点。

To clear the stress relations between bridge decks and the steel tube truss stiffening girder of Zhongxian Yangtze River Bridge, this paper establishes two kinds space analysis model for this bridge, namely: the interaction model of the bridge decks work with the stiffening girder together and the traditional model not work with the stiffening beam.

为了明确忠县长江大桥桥面板与钢管桁架加劲梁的受力关系，本文建立了两种空间分析计算模型，即；桥面系参与加劲梁受力的共同作用模型和不参与加劲梁受力的传统模型。

When train bridge can cause the bridge vibration, the bridge vibration in turn also can affect the vehicles the vibration, namely forms the vehicle bridge coupled oscillation question.

列车过桥时会引起桥梁的振动，桥梁的振动反过来也会影响车辆的振动，即形成车桥耦合振动问题。

Raises comprehensively along with our country railroad passengers and cargo vehicle fast, in order to effective to already has the bridge operation condition to carry on the appraisal by, and to newly built, the reconstruction bridge carries on the optimized design, must carry on the analysis to time the train bridge vehicle bridge coupled oscillation question.

随着我国铁路客货车的全面提速，为了有效的对既有桥梁运营状态进行评估以，及对新建、改建桥梁进行优化设计，均需对列车过桥时的车桥耦合振动问题进行分析。

The structure parameter influences on lateral stability, such as crankle rigidity ratio of arch rib, arch axis coefficient, arch high span ratio, lateral rigidity of bridge decking and arch rib ratio, the effect of non-orientedly conservative loadings of bridge deck, lateral wind loadings were discussed. Corresponding numerical charts were given, and they may be of some reference value and helpful to the parameter design of ribbed arches.2. In this paper, the example bridge is a long-span half-through CFST arch bridge of a 100m span in Yi Lan.

分析了拱肋的抗扭刚度与横向抗弯刚度比、拱轴系数、矢跨比、桥面系的横向抗弯刚度与拱肋的横向抗弯刚度比、桥面系横向刚度引起的非保向力效应、横向风荷载对单肋拱横向稳定的影响，并给出了相应的图表，为拱桥设计时拱肋的结构参数的选取提供一定的依据。

It is showed in wind-vehicle-bridge system vibration analysis that cross wind action can remarkably increase the response of bridge and vehicle. Generally, the response of bridge and vehicle are increased with wind speed and train speed, one case that vehicle is on leeward side of deck is more unsafe than another case that vehicle is on windward side of deck. Nonlinear factors can more influence bridge than vehicle.

风—车—桥系统耦合振动分析结果表明：考虑风的作用会显著增加车辆和桥梁的响应；车辆和桥梁的响应总体上随风速和车速的提高而变大；车辆位于桥道背风侧时较迎风侧时更为不利；非线性因素对桥梁的影响较车辆的要大。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
