The result indicates that three groups of concrete beams strengthened by anchor-bolted steel plate can be loaded as far as they were destroyed; compared with unstrengthened beams ,these beams strengthened by steel plate using adhesive or anchor all can achieve a seventy percent higher loading capacity and thirty percent higher stiffness. On the condition that with the same steel plate ,concrete beams strengthened by bolting steel plate can work as good as those beams strengthened by using adhesive.

试验结果表明：三种锚固布置方式加固梁都能保证钢板与混凝土联合工作直至梁破坏；与未加固梁比较，锚固钢板加固梁和外粘钢板加固梁一样，都能有效提高梁的承载力和刚度，其中承载力提高幅度约为70%；刚度提高约为30%，这说明在钢板量相同的情况下，锚固钢板加固梁能够达到与粘结加固基本相同的加固效果。

The experimental results indicate that the CFRP and steel plate combination strengthening method can effectively improve the load capacity of RC beams, restrict the development of existing cracks andenhance section stiffness, and by using the U style steel plate hoop anchorage system, sudden debonding failures can be avoided.

试验结果表明：碳纤维与钢板复合加固钢筋混凝土梁能有效地提高截面承载力，约束裂缝的发展，提高刚度；加载点及端部采用的U型钢板箍较好地防止了梁中剥离破坏的发生。

The cold-formed sheet is a groove-shaped structure that is composed of a crown plate and reinforced ribs connected with ends of the crown plate; the box beam is a box-shaped structure comprising an upper wing edge, a lower wing edge and two side webs that are connected in every two components.

由压型钢板、纤维增强塑料箱梁组成，压型钢板为由顶板和顶板端部的加强肋相连组成的槽形结构，箱梁为由上翼缘、下翼缘和两侧腹板两两相连组成的箱形结构，其结构如图所示。

In the paper,the equations of motion for the vehicle_bridge_MTMD system are presented and the effectiveness of suppressing the transverse vibration of the deck steel plate girder bridge with multiple tuned mass dampers is investigated by the field test and simulated calculation.

本文建立了车-桥-MTMD系统振动方程，对利用多重调频质量阻尼器抑制铁路上承钢板梁桥横向振动的效果进行了模拟计算和现场试验。

With the theory of energy random analysis of train derailment, the security of moving train on up line and down line of Laoluanhe bridges is analyzed contrastively, and the influence on improving resisting derailment ability of bridges by widening the distance between two main beams of the deck steel plate girder bridge is studied.

进一步运用列车脱轨能量随机分析理论，对比分析了老滦河桥上、下行线上的列车走行安全性，分析了增大钢板梁主梁中心距对提高桥梁抗脱轨能力的影响。

Based on qualitative analysis and comparison of several options for suppressing transverse vibration on deck type steel plate girder of railway bridge,conclusions are made as follows:with static reinforcing,the vibration amplitude can be suppressed to some extent,but quasi-resonance of the bridge can not be avoided,moreover,the construction is inconvenient and costly.

通过对目前抑制铁路上承式钢板梁桥横向振动的几种方案进行定性的分析和比较，认为：静力加固方案可以使桥梁振幅有所减小，但不能避免准共振现象的发生，而且工程造价较高，施工也不方便；两桥连接方案减振效果明显(减振率近50%)，比较经济也比较方便，但同样不能避免准共振现象的发生；动力减振方案可以有效的抑制桥梁的准共振现象(现场试验中减振率达51.83%)，而且工程造价较低，施工简单、方便。

In this paper,the strengthening effect of railway steel plate girders is assessed by using the fuzzy system.

本文利用模糊系统对铁路钢板梁桥的加固效果进行评估。

Due to severe deficiency of vertical and lateral stiffness in most railway steel plate girder bridges after train speeds being raised,the bridge structures of existing railways must be strengthened in order to guarantee the safety of railway transportation.In addition,assessment of strengthening effect has become one of the most important topics in the study of railway steel plate girder bridges.

由于大部分铁路钢板梁桥在列车提速后竖向刚度和横向刚度都存在严重的不足，为保证铁路运输安全必须对其进行加固，而对其加固效果进行准确评估已成为铁路钢板梁桥研究的重要课题之一。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
