To get an exact solution of the forced vibration of the beam bridge under the load of moving vehicles is difficult in the engineering design.

桥梁在移动车辆荷载作用下的振动分析是工程设计中有待进一步解决的问题之一。

If the excitation frequency is close to one of the natural frequencies of the bridge, further analysis is required to determine the dynamic amplification in what is known as a 'forced vibration' analysis.

如果激励频率接近一个自然频率的桥梁，进一步分析必须确定动态扩增什么是所谓的'强迫振动分析。

These bridges were refitted by the US Forest Service to make them safe for biking and walking.

这些桥梁是改装美国林务局，使他们安全的骑自行车和步行。

The equations of motion for vehicle-bridge whole system are formed using conventional finite element method, and they are solved using Wilson-θ method.

按照有限元方法，形成汽车与桥梁相互作用的整体系统方程，并采用Wilson-θ法求解。

Based on the theory of fracture mechanics and the principle of structural reliability analysis,a computation formula of the fatigue failure of suspension cable system in a suspension bridge caused by alternate stress is deduced,thus an evaluation method on the safety life of suspension cable system which has been subjected to eroding is suggested,according to which,highway administration departments can arrange the opportunity of detection,maintenance and strengthening of bridges,as well as the investment.

根据断裂力学理论和结构系统可靠性分析原理，推导出交变应力引起的悬索桥吊索系统疲劳失效的计算公式，从而提出的一种考虑构件腐蚀后吊索系统安全寿命的评估方法，可以为公路管理部门合理安排桥梁的检测、维修、加固的时机和投资提供依据。

So it is very important to adopt the effective seismic fortification measures to insure the safety of the structure in earthquake.

因此，对大跨度斜拉桥结构桥梁采取合理有效的抗震措施以确保其在地震中的安全性，具有十分重要的社会和经济意义。

According to the theoretical analysis and experimental results,it is concluded that the wind swirl and the fosse moat effect can also accelerate the concrete carbonization.Besides,wind pressure can generate secondary air field,which can also accelerate the concrete carbonization.

笔者在对贵州省贵阳铁路分局川黔线上一座使用了34 a的混凝土桥梁进行调研时发现，受风压影响较大面的碳化深度为一般面碳化深度的1.15倍，并在文献[2]中对这一结果进行了简单描述。

There is continually someone brave to be primary to fractious a bridge!

不断有勇敢的人将主要以任性的桥梁！
