[按语]圣地亚哥计划的三座地标桥梁xihu(蝶形拱), xianbi(分离式拱肋单侧吊杆拱), lincong(单肋单侧吊杆拱)于2016年开工。
(1)xihu桥是分离式桥面板,宽肋挖窗空;
(2)xianbi桥,分离式桥面成两个半环,仅在内侧设双吊杆,分别挂到两个拱肋上,成双肋交叉四索面。肋上两侧吊杆斜度不同,恒载扭矩虽然可以用偏心调整为零,但是恒载水平分力有微小不平衡,所以拱肋不能平行,需要略略张开些,用肋重的水平分力来平衡;
(3) lincong桥正常布置
(4)三座桥都注重桥梁底面设计,以供桥下观赏。xihu桥、lincong桥设岸滩人行拱形通道,使得桥梁正面图呈现新月形。

spanish architect santiago calatrava has been commissioned to design three landmark bridges in the rapidly expanding chinese city of huashan. located in the province of hubei, the crossings will facilitate cars, pedestrians and cyclists across the city’s newly-constructed yangtze river canal. the trio of steel spans — called ‘xihu’, ‘xianbi’, and ‘lincong’ — are carefully integrated with the existing pedestrian and bicycle network through a series of stairs and ramps. these routes also provide key access points between the road and the promenade pathways at canal level.

the ‘xianbi bridge’, the central crossing, is 129 meters long with an arch soaring to a total height of 42.3 meters. the design incorporates two traffic lanes with a support structure in the center, creating a characteristic void. the westernmost ‘xihu bridge’ has been conceived with a single arch, and is connected via a platform of inclined corrugated cables. it is 102.7 meters long and the tied arch reaches 20.4 meters. finally, the ‘lincong bridge’ has two arches inclining outwards, reaching 118 meters in length.

architecture is one of the art forms best able to improve and revitalize cities both artistically and functionally,’ commented calatrava‘the huashan project is a clear example of how an urban element, key to the successful growth of the city, can at the same time improve the quality of life for its citizens, thanks to an integration of all three bridges and the creation of boulevards on the banks of the canal.’

 

construction work is expected to begin in late 2016.
