桥墩

Horizontal push will arise Pier displacement of the through arch bridge of concrete-filled steel tubes under the condition of erection of arch ribs , concreting process, transverse beam pouring and installation.

下承式钢管拱系杆拱桥在拱肋安装、钢管混凝土浇筑、横梁安装和现浇横梁、桥面板湿接头时对拱脚产生的水平推力极易造成桥墩位移，通过对不同过程中的水平力计算，确定体外束张拉方案，使水平力通过体外束得以平衡。

According to the bridge pier, the in-situ check dam and four protection measures, seven sets of experiments were carried out.

针对桥墩形状、既有固床工及四种保护方案，进行了七组水工试验，加上模拟上游进砂的情形一组，总共为八组试验。

The shaking table test for submerged bridge pier with pile foundation was performed.

进行了水下桩基础桥墩的振动台试验研究。

And the deformation and stability analysis of pile foundation with high bridge pier are important technical problems on the basis of understanding the structure characteristics of bearing mechanics.

此时，如何在全面掌握高桥墩桩基础承载机理的基础上进行其变形与稳定性分析，已成为山区高架桥基础工程所面临的重要技术难题。

And the rational design of pile foundation with high bridge pier is an important technical problem on the basis of understanding the structure characteristics of bearing mechanics, deformation and stability.

因此，如何在全面掌握高桥墩桩基础承载机理、变形与稳定特性的基础上，对其进行合理设计，目前已成为山区高架桥基础工程所面临的重要技术难题。

Then a two-particle model with an actual structure as the background is established to study the dynamic interaction between the high-rise pile cap foundation and bridge structure.

结果表明，承台质量较大的高桩承台基础和基础以上桥梁结构之间的动力相互作用现象非常显著，计算桥墩和基础的地震反应时，承台质量的影响不可忽略，否则可能会引起很大的误差。

For example, is a bust portrait of a PLA soldier who is pleasantly posing in front of the Nanjing Yangtze River Bridge.

画中的大桥只能看见局部，它从画面的左下方向右上方成斜角延伸，其中的一个巨大桥墩似乎穿过桥面而向空中挺立。

There are six typical migrating pingo s along the Qinghai-Tibet Railway and freezing and swelling of some of these pingos caused fracturing of bridge piers and culverts and bending of oil pipelines along the railway and highway.

青藏铁路沿线发育6个典型移动冰丘，冰丘冻胀对线路工程具有严重破坏作用，导致桥墩扭裂、涵洞破裂与输油管道弯曲变形，产生显著的灾害效应。

Three dimensional numerical modeling on migrating pingo destructing bridge pier can provide important factors for designing bridge and protecting geological hazard in permafrost.

移动冰丘导致桥墩变形破坏的三维有限元数值模拟能够为常年冻土区桥梁工程设计和地质灾害防治提供力学参数和科学依据。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
