項(xiàng)目背景
Background
元蕩，地處滬蘇邊界，與淀山湖相接，因蘆灘封淤而成為淀山湖的一個(gè)子湖。當(dāng)?shù)厮W(wǎng)密布，村落眾多。原兩岸雖僅一衣帶水，但來往不便。
The Yuandang Pedestrian Bridge celebrates coming together of Jiangsu Province and Shanghai.
如今，環(huán)元蕩貫通橋（以下簡稱“元蕩橋”）連通上海青浦與江蘇吳江的兩岸，加速長三角一體化示范區(qū)的發(fā)展進(jìn)程，這也是該示范區(qū)的首座新建慢行橋。
The 586m bridge is a hybrid structure incorporating landscape, infrastructure, and architecture. It is located in a key location where the two jurisdictions meet.
銜接風(fēng)貌：糅合本土元素
Blending with local elements
元蕩橋全長586米，整體設(shè)計(jì)以“同心結(jié)”為理念，體現(xiàn)青吳兩地同心共治的發(fā)展愿景。橋身如同一條緞帶，連同揉入湖水柔波元素的橋上欄桿，與元蕩湖上的水波交相呼應(yīng)。景亭中的太湖石小品，靈感源自當(dāng)?shù)貍鹘y(tǒng)雕塑，設(shè)計(jì)上探索了當(dāng)代數(shù)字建模及制作，創(chuàng)造了既是雕塑又是游樂場的多孔墻。
The figure of the bridge resembles a ribbon and echoes water ripples on the Yuandang Lake below.
橋上橋下的綠化種植延續(xù)了兩岸生態(tài)公園的原生態(tài)種植理念，結(jié)合對本土植物及動物的思考。將樹木和灌木融入到橋中，構(gòu)建了一座連接兩岸的浮動花園。這些融入本土環(huán)境的巧妙設(shè)計(jì)，使整座橋梁成為元蕩湖上的一道別致景觀。與此同時(shí)，元蕩橋也串聯(lián)了周邊千帆歸渡、閑夢云臺、汾湖之眼等旅游資源，形成一段連續(xù)的生態(tài)之旅。
Trees and shrubs are incorporated in the bridge, giving the appearance of a floating garden connecting the two banks.
移步異景：特色線性安排
Cycling path, vegetation band and walking path
元蕩橋的橋面標(biāo)準(zhǔn)段橫斷面布置為：2m（人行道）+2m（綠化帶）+2m（自行車道）=6m，分為騎行、慢行、綠化三條線性，多種情境和氛圍在橋面交織。
The six-meter-wide bridge deck is divided into three bands: cycling path, vegetation band and walking path. The winding bridge has three widened sections for resting and enjoying the lake view.
在行進(jìn)的方向上，步行者和騎行者進(jìn)入不同的線路，綠化帶將兩者間隔開來，這種線性設(shè)置為當(dāng)?shù)鼐用竦慕】瞪顒澐职踩吔?。曲橋有三個(gè)加寬的部分，各條線路相合，并加入休閑長凳、觀景平臺、景觀亭等，可供游人休憩及觀賞湖景。這種線路設(shè)計(jì)延續(xù)了江南文化的動觀為游，妙在步移景異，奇在風(fēng)景如畫。游賞相間，動靜交替則元蕩湖之景致盡入眼中。
Taking inspiration from local sculptural traditions, the bridge’s pavilion explores contemporary mathematics modeling to create a porous wall that is both sculpture and playground.
結(jié)語
Epilogue
元蕩橋是一個(gè)集生態(tài)、交通、景觀、文化于一體的動態(tài)整體。橋梁的建設(shè)使吳江、青浦的生態(tài)景觀保持連續(xù)性，形成和諧統(tǒng)一的藍(lán)綠慢行體系，從而提升元蕩湖區(qū)域的環(huán)境品質(zhì)。它的建成既實(shí)現(xiàn)了兩區(qū)藍(lán)綠體系直接聯(lián)通，也滿足當(dāng)?shù)鼐用裼斡[、休閑、觀賞等需要。
The bridge is a dynamic ensemble, integrating ecology, transportation, landscape, and culture.
