拱桥 Arch Bridges
拱桥是我国最常用的一种桥梁型式，其式样之多，数量之大，为各种桥型之冠，特别是公路桥梁，据不完全统计，我国的公路桥中百分之七为拱桥。由于我国是一个多山的国家，石料资源丰富，因此拱桥以石料为主。建于公元1990年，跨径120m的湖南乌巢河大桥，是当今世界跨径第一的石拱桥。我国建造的钢筋混凝土拱桥的形式更是繁花似锦，式样之多当属世界之最，其中建造得比较多的是箱形拱、双曲拱、肋拱、桁架拱、刚架拱等，它们大多数是上承式桥梁，桥面宽敞，造价低廉。
箱形拱主要用于大跨径。四川涪陵乌江大桥，跨径200m，是我国已建成的最大跨径的箱形拱，跨径420m的万江大桥正在设计中，它将是世界最大跨径的钢筋混凝土拱桥。双曲拱是我国首创并不断改进的一种新型钢筋混凝土拱桥，它发源于江苏无锡，遍步各地，最大跨径当推河南前河大桥，跨径150m；桁架拱是在软土地基上为了减轻自重、改善拱上建筑与主拱圈共同作用，藉桁架原理逐步发展起来的一种轻型钢筋混凝土拱桥，适用于中小跨径桥梁。当采用了预应力措施和悬臂拼装的方法，就形成一种悬臂组合桁架拱桥，正在建造的贵州江界河大桥，主跨330m，是国内最大跨径的在建拱桥。四川宜宾小南门大桥为跨径240m的中承式肋拱，是我国该种桥型的最大跨径。刚架拱桥是从简化拱上建筑着眼，利用斜撑将桥面最不利荷载位置的荷载传至拱脚，以改善主拱的受力，在江苏无锡建成了跨越大运河的三座跨径100m的钢筋混凝土刚架拱。在我国也建有一定数量的下承式钢筋混凝土肋拱，其中有的是系杆拱或刚拱刚梁组合拱，后者是跨径100m册中承式无铰拱；我国还修建了一些钢拱桥及斜腿刚架桥。
我国在建造钢筋混凝土拱桥的实践中进行了拱轴线优化，混凝土徐变对混凝土拱内力重分布影响、连拱计算、拱桥荷载横向分布、各种形式拱桥的设计计算理论的创立与完善、组合装配式混凝土拱桥的施工控制等研究。为了适应在软土地基上建造混凝土拱桥，提出了组合桥台形式与其计算理论。在拱桥施工方法上也有所创新：如中小跨径拱桥以预制拱肋为拱架，少支架施工为主，或采用悬砌方法；大跨径拱桥则采取纵向分条，横向分段，预制拱肋，无支架吊装，组合拼装与现浇相组合的施工方法；此外，在采用无支架转体施工方法建造拱桥方面也有不少成功的经验。
Of all types of bridges in China, the arch bridge holds the leading role with its greatest variety and largest magnitude. And especially, arch structure is widely used for highway bridges. The statistics from all the sources available show that around 70% of highway bridges are arch bridges. China is renowned for its mountains with an abundant supply of stone. So, stone has been used as the main construction material for arch bridges. The Wuchao River Bridge in Hunan Province, for instance, with a span of 120m, is the longest stone arch bridge in the world. However, China's reinforced concrete arch bridges are unparalleled in the world for their various forms and styles.
Most of the arches used in our country fall into the following categories: box arch, two-way curved arch, ribbed arch, trussed arch, and rigid framed arch. The majority of these structures are deck bridges with wide clearance, and it costs less to build such bridges. Box arch is especially suitable for long-span bridges. The longest stone arch ever built in China is the Wujiang Bridge in Beiling, Sichuan Province, whose span is as long as 200m. The project over the Yangtze River in Wan County, Sichuan Province with a spectacular span of 420m will set up a world record in concrete arch literature when it is completed. A unique and successful improvement of reinforced concrete arch, the two-way curved arch structure, which originated in Wuxi, Jiangsu Province, has found wide application all over the country, thanks to its advantages of saving labour and falsework. The largest span of this type goes to the 150m-span Qianhe River Bridge in Henan Province, built in 1969. Trussed arch with light dead weight performs effectively on soft sub-soil foundations. It has been adopted to improve the composite action between the rib and the spandrel. On the basis of the truss theory, a light and congruous reinforced concrete arch bridge has been gradually developed for short and medium spans. Through prestressing and with the application of cantilevering erection process comes into being a special type of bridge known as "cantilever composite trussed arch bridge". An example of this type is the 330m-span Jiangjie River Bridge in Guizhou Province, which is still under construction at present. When completed, the bridge will be the largest arch bridge in China. The Little South Gate Bridge, situated in Yibin City, Sichuan Province, is a half through ribbed arch bridge with a span of 240m, the longest of its kind. With a simplified spandrel construction, the rigid framed arch bridge has a much better stress condition on the main rib by means of inclined struts, which transfer to the springing point the force induced by the live load on the critical position. In the city of Wuxi, Jiangsu Province, three such bridges with a span of 100m each were erected in succession across the Great Canal. Besides, quite a number of ribbed arch bridges have been erected, either with tie arches or with Langer's girders. The recently completed Wangcang Bridge in Sichuan Province and the Gaoming Bridge in Guangdong Province are both steel pipe arch bridges. The former has a 115m prestressed tie arch, while the latter, a 110m half through fixed rib arch. In our country, there have also been constructed a few steel arch bridges and slant-legged rigid frame bridges.
Along with the construction of reinforced concrete arch bridges, researches on the following topics have been carried out: optimum arch axis locus, redistribution of internal forces between concrete and reinforcement caused by concrete creep, analytical approach to continuous arch, and lateral distribution of load between arch ribs. Besides, design approaches to various types of arch have been formulated and revised. The erection of composite precast reinforced concrete arch bridges can now be controlled. The construction of combined abutment with its design theory has been introduced, which is adaptable to the building of arch bridges on soft subsoil foundations.
In addition, modern techniques have been attained that may solve the problems arising in bridge construction. In building arch bridges of short and medium spans, precast ribs are used to serve as temporary falsework. And sometimes, cantilever paving process is used. Large span arch bridges are segmented transversely as well as longitudinally. With precast ribs, a bridge can be erected without scaffolding, its components being assembled, complemented by cast-in-situ concrete. Also, successful experience has been accumulated on arch bridge erection, particularly the erection by the method of overall rotation without any auxiliary falsework or support, which has proved feasible and successful.

无锡卫东桥、民主桥 Weidong Bridge Minzhu Bridge
双曲拱桥最早是建造在江苏省无锡县境内、无锡桥梁工程队首创的一种新型拱桥。其结构特点是施工中将拱桥化整为零，预制、组合拼装与现浇混凝土相结合。主要构件有拱肋、拱波、横梁或拉条以及拱上建筑的各种部件。其中拱肋是施工阶段的拱架，又是主拱圈的主要组成部件，分段预制的拱肋在支架上拼装或无支架悬吊拼装，成拱后，再在其上砌置拱波，浇筑拱背混凝土，然后设置拱上建筑并浇筑桥面。拱肋有矩形、倒T形、V形以及箱形等截面型式，在中小跨径的双曲拱桥中，也有将肋波结合、整体浇筑，作预制吊装段，称为整体波。
卫东桥、民主桥都是无锡县桥梁工程队（现称无锡桥梁工程公司）设计、施工的，前者结构纤细轻盈，适宜于软土地基上建造；后者构思独特，充分发挥双曲拱桥构造特点，组合拼装成三叉形的双曲拱桥。
