文中根据铁道部对通用参考图《铁路箱梁平面布置》的编制要求，结合笔者主持和参与的多个科研课题研究成果和对预制场的平面布置设计经验，从编制通用参考图的角度对《铁路箱梁预制场平面布置图》的编制原则进行论述。

The design of the automatic grabbing beam always uses the grabbing beam which has built indiscriminately or refits itl The trchnology is mature though the lack of a set of perfect standards.

自动抓梁的设计一直是根据工程实际套用或改装已建工程的抓梁，虽然没有一套完整的标准，但技术已经成熟。

In this report, we first make a review of the retrofit methods in the literatures and provide design equations for retrofit of the beams and columns. Then we will use four school buildings as examples to design their ductility retrofits

文中先对文线上的补强工法作一回顾，并对梁及柱的韧性补强设计提出设计公式，在文后以四栋学校建筑为例，做出梁及柱的韧性补强设计。

In this paper, the dynamic characteristics of a beam with viscous damping layers are studied. For convenience to analyze by transfer matrix method, the concept of equivalent dissipated energy is utilized to transform the damping layers to be uniformly soloed into the beam body without changing thesis damping effect.

中文摘要本文是以梁含有黏滞阻尼作动态特性研究，为了方便作分析，本文利用传递矩阵法作分析，再以消散能等效原理，将阻尼均匀融入在主梁其不改变阻尼效益。

The basic frequences of the two types of bridges are heightened by increasing vertical curve curvature of stiffening girder, setting vertical supporting members and stiffing connection.

增大加劲梁竖曲线曲率，桥塔处设置竖向支撑和缆梁跨中固结均能提高悬索桥的自振基频。

The tensioning of the steel wires is the key step in the construction process.

预应力施工对于预应力弯箱梁桥至关重要，而预应力钢束的张拉是弯箱梁施工中的关键工序。
