摘要
本文主要探讨了简支转连续梁桥体系，以及其研究背景、发展历程、国内外简支转连续梁桥体系的研究状况、桥梁建设的创新、总结目前存在的问题与对未来的展望。在城市化进程无比迅速的今天，建立一个通行顺适的交通网络显得尤为重要。当代人追求桥型美观简洁，通行平稳快捷，这对于简支转连续梁桥的推广无疑是巨大的利好。由于简支转连续梁桥制造工艺相对简单，安装施工较为方便，在城市道路桥梁中得到了广泛的应用。其中的简支转连续小箱梁桥在30-40米跨径的城市桥型中占有较大比重，且其占比仍在上升，是城市交通建设的优势桥型。文章也就简支转连续梁桥体系的研究难点做了总结，学习归纳了一部分简支转连续梁桥的优点与缺点。

ABSTRACT
This paper mainly discusses the simple continuous box beam bridge system, as well as its research background, development process, research status of simple continuous box beam bridge system at home and abroad, innovation of bridge construction, summary of existing problems and future prospects. In the rapid process of urbanization today, it is particularly important to establish a smooth traffic network. Contemporary people pursue beautiful and simple bridge type, smooth and fast traffic, which is undoubtedly a great advantage for the promotion of simply supported continuous beam bridge. Due to the relatively simple manufacturing process and convenient installation and construction of simply supported continuous girder bridge, it has been widely used in urban roads. Among them, the simple continuous box beam bridge occupies a large proportion in the urban bridge type with 30-40 meters span, and its proportion is still rising, which is the dominant bridge type in urban traffic construction. This paper also summarizes the research difficulties of simple continuous box beam bridge system, and summarizes the advantages and disadvantages of some simple continuous box beam bridges.
