18、，橋面寬敞，造價低廉。 箱形拱主要用于大跨徑。四川涪陵烏江大橋，跨徑200m，是我國已建成的最大跨徑的箱形拱，跨徑420m的萬縣長江大橋正在設(shè)計中，它將是世界最大跨徑的鋼筋混凝土拱橋。雙曲拱是我國首創(chuàng)并不斷改進(jìn)的一種新型鋼筋混凝土拱橋，它發(fā)源于江蘇無錫，遍步各地，最大跨徑當(dāng)推河南前河大橋，跨徑150m；桁架拱是在軟土地基上為了減輕自重、改善拱上建筑與主拱圈共同作用，藉桁架原理逐步發(fā)展起來的一種輕型鋼筋混凝土拱橋，適用于中小跨徑橋梁。當(dāng)采用了預(yù)應(yīng)力措施和懸臂拼裝的方法，就形成一種懸臂組合桁架拱橋，正在建造的貴州江界河大橋，主跨330m，是國內(nèi)最大跨徑的在建拱橋。四川宜賓小南門大橋為跨徑240m的

19、中承式肋拱，是我國該種橋型的最大跨徑。剛架拱橋是從簡化拱上建筑著眼，利用斜撐將橋面最不利荷載位置的荷載傳至拱腳，以改善主拱的受力，在江蘇無錫建成了跨越大運河的三座跨徑100m的鋼筋混凝土剛架拱。在我國也建有一定數(shù)量的下承式鋼筋混凝土肋拱，其中有的是系桿拱或剛拱剛梁組合拱，后者是跨徑100m冊中承式無鉸拱；我國還修建了一些鋼拱橋及斜腿剛架橋。 我國在建造鋼筋混凝土拱橋的實踐中進(jìn)行了拱軸線優(yōu)化，混凝土徐變對混凝土拱內(nèi)力重分布影響、連拱計算、拱橋荷載橫向分布、各種形式拱橋的設(shè)計計算理論的創(chuàng)立與完善、組合裝配式混凝土拱橋的施工控制等研究。為了適應(yīng)在軟土地基上建造混凝土拱橋，提出了組合橋臺形式與其計算理

20、論。在拱橋施工方法上也有所創(chuàng)新：如中小跨徑拱橋以預(yù)制拱肋為拱架，少支架施工為主，或采用懸砌方法；大跨徑拱橋則采取縱向分條，橫向分段，預(yù)制拱肋，無支架吊裝，組合拼裝與現(xiàn)澆相組合的施工方法；此外，在采用無支架轉(zhuǎn)體施工方法建造拱橋方面也有不少成功的經(jīng)驗。 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 hig

21、hway 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 Pro

22、vince, for instance, with a span of 120m, is the longest stone arch bridge in the world. However, Chinas 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 cur

23、ved 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 Beili

24、ng, 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 tw

25、o-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 wi

26、th 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 span

27、s. 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 pre

28、sent. 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

29、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

30、Great Canal. Besides, quite a number of ribbed arch bridges have been erected, either with tie arches or with Langers 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 t

31、ie 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: op

32、timum 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

33、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 tha

34、t 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 pre

35、cast 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 supp
