桥梁

In this paper, the seismic response of a high pier three-span continuous box girder bridge is detailed calculated, and the measures that prevent beam down and crushing pillar to damage of the structure in big earthquake is advanced.

通过时一座高墩三跨连续箱梁桥的地震响应进行数值模拟计算，分析了高墩桥梁的地震响应特点，提出了高墩桥梁在大震作用下应采取防止落梁及墩柱压渍破坏的构造措施。

This paper is based on the former research taking the No.1 Tong-Lv Bridge as an example; the large universal finite element program Midas/Civil is adopted, a three-dimensional finite element model is established. The static performance, the comparative analysis of influence surfaces, the experimental study and the analysis of a local finite element model of the new style three-span continuous through type bow-string arch bridge is made. With these studies, this paper is aimed at revealing the performance of this kind of construction.

本文在前人研究的基础上，以通吕一号桥为背景，采用空间有限元法对结构形式新颖的三跨连续下承式系杆拱桥的静力性能、影响面比较分析、实桥荷载试验、局部节点分析等进行研究，旨在深入理解该结构形式桥梁的力学性能，为今后相同结构体系桥梁的结构分析提供可以参考的建议。

Considering all of above, combined the subsection of "the study of the repair and strengthening method for existing bridge" with the sustentation fund of Ministry of Education, the bond characteristic, failure mechanism and shear strength computation of interface between new and old concrete and their applications in bridge strengthening are studied through the model test with embedded bar or not. The research works are mainly concerned with the following aspects: Firstly, considering different influence factors, the full-range shear experiment of 6 groups with 18 Z-shape specimens is executed. The bond shear capacity of interface is studied as well as the degree of influence such as interface roughness, agent, strength of new and old concrete, the depth of embedded bar.

本文围绕教育部《高等学校优秀青年教师教学科研奖励计划》之子课题&既有桥梁的维修加固方法研究&，结合有和无植筋状况下的模型试验，研究新老混凝土结合面的粘结性能、粘结破坏机理和粘结抗剪强度的计算及在桥梁加固中的应用。

Because the waterproofing question on the concrete bridge deck has not been regarded enough, the concrete bridges were always destroyed prematurely. Especially all kinds of damages occurred on the bridge deck pavement, which have directly influenced safety of steering and the duration of bridge structures and have done a lot of traffic inconvenience and have caused huge economic loses and have not achieved the anticipated economic efficiency.

混凝土桥梁，由于防水问题一直没有得到足够的重视，导致其过早地遭到破坏，尤其沥青混凝土桥面铺装层普遍出现了各种病害，直接影响了行车的安全和桥梁结构的耐久性，给交通带来了很大的不便，造成了巨大的经济损失，没有达到预期投资的经济效益。

At the same time, companies or sectors of China's steel bridge leading enterprises, is a major railway bridge manufacturer of steel structures.

同时，公司还是我国桥梁钢结构行业的龙头企业，是国内大型铁路桥梁钢结构的制造商。

Chinese steel companies bridge the industry leading enterprises, is a major railway bridge the only manufacturer of steel structures.

公司还是中国桥梁钢结构行业的龙头企业，是国内大型铁路桥梁钢结构的唯一制造商。

With the long-span bridges, truck and design speed of the continuous growth of the bridge a more accurate modeling, Analysis and the stress and strain, such as a more important practical significance.

随着桥梁在跨径，载重和设计时速的不断增长，对桥梁进行更为精确的建模，受力分析和应力应变等具有更加重要的现实意义。

The Aioi Bridge, one of 81 bridges connecting the seven-branched delta of the Ota River, was the aiming point of the bomb.

该aioi的桥梁，其中81桥梁连接7支三角洲地区大田河，是瞄准点，该炸弹。

This text has proposed being in the evaluation approaches of the safety of CFST Arch Bridge based on RBF network, applied this approach to the project instance and made certain achievement.

具体做了以下主要工作： 1、本文在现有桥梁安全性评价的基础上，深刻阐述了桥梁安全性评价的内涵。

I will endeavour to find you some assistance.
