廈門和美橋是一座橋面呈弧形的單索吊橋，具有217m 的懸空跨度，是世界上同類橋梁中最長的。它在廈門山海健康步道項目的設計和施工方面都具有很突出的特點。和美橋是廈門市發(fā)起的長達23km 的廈門山海健康步道項目中的標志性橋梁之一，該項目旨在連接城市中心和島內(nèi)的周邊環(huán)境。項目中，7 座設計不同的大跨度橋梁跨越現(xiàn)有的基礎設施或自然地形，明顯有別于常規(guī)人行步道的單調。

一條安全通道

和美橋位于項目中最顯眼的位置，因為大多數(shù)來廈門的游客通過海滄大橋進入廈門島時都會從橋下經(jīng)過。橋的支撐桿件與橋面的雕塑般的外觀呈現(xiàn)出歡迎到達廈門游客的姿態(tài)。它為仙岳公園和虎尾山公園之間的步行者提供了一個安全、無交叉的通道。它將橋上緩慢移動的行人交通與橋下17 條車道上高速移動的車輛交通分開。彎曲的橋面和諧地連接了橋兩端的人行道。

針對特殊環(huán)境的設計

街道的布局和橋梁兩端的陡峭斜坡限制了橋墩的可用空間，使其成為一個大交通島。橋梁設計反映了這些獨特的邊界條件，只需要一個單索支撐桿件。彎曲的橋面與單索吊桿相結合，形成了一個可以支撐近217m 懸空跨度的結構系統(tǒng)。由于扭力和彎矩都相對較小，彎曲的橋面使采用纖薄的橋身截面成為可能。通過橋梁空心箱體部分的上翼緣的壓縮環(huán)和下翼緣的拉伸環(huán)傳遞由偏心布置的懸索產(chǎn)生的旋轉力矩。

輕型結構設計

精心設計的細節(jié)凸顯了該橋的鮮明特性和背后的輕型結構設計理念。所有的細節(jié)都是精心設計的，暴露在外，并減少到結構允許的最低限度。因此，知識淵博的觀察者可以讀懂并跟蹤力的傳導，力通過拉索和鋼結構工程到支撐桿件底部壯觀的球形軸承。

Xiamen's Hemei Bridge is a mono-cable suspension bridge with a curved deck and a free span of 217 m– the longest of its type in the world.It stands out in terms of design and construction in the Xiamen Mountains-to-Sea Trail project.The Hemei Bridge is one of the signature bridges in the 23-kilometer-long mobility project Xiamen Mountains-to-Sea Trail (former Xiamen Health Footpaths) initiated by the City of Xiamen to connect its urban centres with the surrounding nature on the island.In this project,seven largespan bridges span over existing infrastructure or natural topology and their different designs are intended to stand out from the simplicity and repetitiveness of the regular footpath.

A Safe Passage

Hemei Bridge is located at the most prominent spot among them,as most visitors to Xiamen pass under the bridge when entering the Island via Haicang Bridge.The sculptural appearance of the bridge mast and bridge deck creates a welcoming gesture to visitors arriving to Xiamen.It provides a safe and intersectionfree passage for pedestrians between Xianyue Park and Huweishan Park.It decouples slowmoving pedestrian traffic on the bridge from the fast-moving vehicular traffic on the 17 lanes below.The curved bridge deck harmoniously connects the trajectories of the pedestrian walkway at both ends of the bridge.

置身現(xiàn)場會感到設計的結論被證實，圖紙上的效果被放大了。大橋與周圍的環(huán)境融為一體，它的輕質結構、拉索和纖薄的橋面使大橋看起來好像毫不費力地懸浮在繁忙的街道之上。□（葉揚 譯）

評審評語

廈門和美懸索橋全長217m，提供了一條幾乎漂浮在空中的人行道和自行車道，為高速公路交叉口兩側的兩個公園之間提供了一個安全的非機動車通行方式。這座橋橫跨17 條車道，體現(xiàn)出毫不費力的優(yōu)雅和杰出的材料智慧，將創(chuàng)新的工程變成了一種日常的奇遇。憑借其凌空高度、景觀視野和優(yōu)雅曲線，以及兩個橋頭的休憩場所，這個原本功能性的城市基礎設施成為了真正的藝術品，為人們提供驚艷美景和非凡體驗。在黑暗的隧道中穿越交通干線原本并不令人愉悅，卻在這里成為了一種別致的體驗，值得人們專程到訪。

4 平面Layout

The layout of the streets and the steep slopes at both ends of the bridge limit the available space for bridge piers to a large traffic island.The bridge design reflects these unique boundary conditions and requires only one guyed mast.Combining the curved bridge deck with a monocable suspension bridge results in a structural system that can overcome a free span of nearly 217 m.The curved bridge deck allows for a very slender deck cross-section,as both torsion and bending moments are comparatively small.The rotating moment created by the eccentrically arranged hanger cables is transferred through a compression ring in the upper flange and a tension ring in the lower flange of the hollowbox section of the bridge.

Construction of a Light-Weight Design

Carefully designed details underline the honest character of the bridge and the light-weight design philosophy behind it.All details are wellengineered,exposed and reduced to the structural minimum.Thus,the knowledgeable observer can read and follow the flow of forces through the cable net and steel work to the spectacular spherical bearing at the base of the mast.

A visit to the site amplifies the conclusions from the drawing board.The bridge fits into its surroundings and its light-weight construction with its cable net and slender bridge deck make the bridge seem as if it hovers effortlessly above the hectic streets.□

Jury Statement

The 217 m long Hemei Suspension Bridge in Xiamen provides an almost floating pedestrian and bicycle path that makes a safe connection for non-automobile mobility between two parks on either side of a junction of highways.Bridging 17 car lanes with effortless elegance and great material intelligence the project turns innovative engineering into an everyday adventure:with its height,views,elegance and curve,as well as places to rest on either bridgehead a piece of functional urban infrastructure becomes a thing of real beauty and provides an exceptional experience with amazing views.The otherwise unpleasant practice of having to cross traffic arteries in dark tunnels is turned into an exquisite occasion well worth a special visit.
