伴随着材质(这里的材质主要指的是高强度的钢材以及各种耐候钢)的不断提高以及包括焊接工艺以及高强螺栓连接等工艺技术的不断发展完善,制作架设比较容易的箱型截面得到了很快的发展,钢桥的发展也逐渐的朝着大跨度、轻材质、高强度、美观以及快速施工等方向前进。但是随之而来的就是桥梁加固施工技术的不断深化,文章就针对这个大的背景以及结合现代化发展的需要对问题进行了讨论。
Accompanied by continuous improvement of the material (the material here mainly refers to the high-strength steel and various weathering steels), as well as the continuous improvement of the process technology including the welding process and the high-strength bolt connection, a box-shaped section that is relatively easy to set up is obtained The rapid development of the development of steel bridge gradually toward large-span, light material, high strength, beautiful and rapid construction and other forward. But what followed was the deepening of bridge reinforcement construction technology. The article discussed the issue in response to this large background and the need of the modernization development.
