本文将向大家介绍来自奥地利penda工作室的圆环桥方案、巴西JBMC工作室的剪开的“管道”方案和美国Standard建筑事务所的方案。今年11月底将公布本次比赛的最终优胜方案。
这是奥地利建筑师Alex Daxb?ck和Chris Precht组建的penda工作室带来的圆环桥（The O）方案——从方案的名字你就可以知道该方案的 最大特色。和大多数斜拉桥所采用的垂直桥墩不同，该方案将由一个闭合的倾斜圆环起到桥墩的作用，而桥梁本身则从圆环中心穿过，横跨河的两岸。除了美观上的考量，这个圆环也有实际的作用——整个桥的主体结构为全钢材质，圆环上遍布的钢索，则起到传导的作用，将整个桥的重量传递到了河道高坡上的混凝土基础之上，从而减轻了桥给两岸造成的压力。
圆环桥（The O）方案非常吸引人们眼球，犹如一个舞者在那里翩翩起舞。它重新诠释了传统桥梁，其标志性的造型与当地的传统与优雅协调，十分得体地欢迎到访者，并根据来访者位置的移动发生着改变，完成了与人的交互。桥体一侧林着繁忙的道路，一侧联系美丽的草甸，人们从侧面看构架轻盈，逐渐转到正面，构架在视线中从线逐渐变成一个椭圆，最后再到气场十足的正圆，给人们留下了深刻的印象，完成振奋人心的过渡。从东西方向来看，该建筑几乎为二维结构；而南北方向则是立体又三维的结构。建筑采用桁架系统，木质的步道，流畅的扶手。人行道最终通向一个阶梯状的大草坪，可用于休闲活动或者露天影院。大桥的主要构建使用焊接钢管，利用日间悬索吸收的太阳能，为夜间的LED灯提供电力，确保夜间照明。
桥面铺上木甲板，栏板为半透明同时轻微向外侧倾斜，呈开放欢迎的姿态迎接过往人群。桥体上那引人注目的钢环由异型钢管焊接而成，钢索牵引着钢环，最后将力传递到河道高坡上的混凝土基础之上，减轻了桥体在两岸的落脚荷载。夜晚，LED灯照亮了桥体，这座桥是一个优雅的元素，它全天候的融入这片土地，为当地还有附近的人们带来不一样的意义和印象。
changing its appearance depending on the angle of approach, this proposal for the meadows salford bridge competition by designers alex daxb?ck and chris precht of penda features a strong elliptical shape. the project offers a dominant visual landmark that when viewed from its side looks like a regular suspended bridge, but as one gets closer the structure opens up to a rounded volume, engulfing pedestrians as they cross over to the meadows. the multifaceted object is in contrast to its surrounding harmonious green spaces. the crossing is presented as a disco-like object when viewed from the south and north, whereas from the western and eastern sides it looks slim and elegant, almost two-dimensional. constructed using a truss system that supports a wooden pathway with glazed semi-transparent handrails with both of its endings generously widened, inviting pedestrians on its platform. the walkway merges onto a terraced landscape, which can be used for lounging and as an open air theater. the main structural element is made using a welded steel tube that rests on two concrete bearings, supporting and carrying the weight at the same time. during the day the suspension cables reflect the sunlight, while the sun's energy is stored in energy saving LED's, allowing the bridge to glow during the night.
巴西JBMC建筑事务所的设计方案呈现出管状，将为新的城市景观大道吸引人气。该项目结合了功能性与标志性，从Chapel街廊道引出的一个三角形铺道广场形成了其闪亮耀眼的入口。外层黄铜色表皮类似船体结构，随河流角度弯曲，模糊淡化了结构内外的边界。回环的桥身提供了丰富多变的视野，逐渐显露出周围的环境，包括Irwell河、繁茂的的林地和草地。为了加深变化景观对人们的印象，桥身在中间最宽处达到360度赏景角度。
alluring pedestrians onto a new urban promenade, brazilian architecture firm JBMC have proposed a tube-shaped structure for the meadows salford bridge competition. the project combines both a functional crossing with an iconic landmark, from the chapel street corridor a triangular paved square frames its shiny opening. an outer copper skin resembles the hull of a ship as it gently curves along the river, helping to blur the boundary between the structure’s interior and exterior. the journey along the rotating form offers a series of changing views that gradually reveal the surrounding environment – the irwell river, the dense woodland and the meadows. to enhance this changing perspective the floor widens, reaching it widest point in the middle with 360 views over the landscape. this organic progression across the river helps to connect two distinct environments. upon reaching the other side, a smoothly sloping plateau drops towards the meadow – a welcoming introduction to the new landscape.
the structural design is based on traditional naval construction, it applies a longitudinal keel and transverse frames. the use of helical bracing, with two opposing helical halves provides a level of stability that follows the varying height. materials were chosen in regards to their simplicity, the use of prefabricated steel elements can easily be assembled on-site. locally sourced, reforested treated wooden planks are placed on the internal deck floor, these adjust to the natural curvature of the bridge. finally, the changing colors of the copper skin help to blend the urban surroundings with the green landscape.
STANDARD shared with us their design for the Salford Meadows Bridge Competition.
The new Salford Meadows Bridge forms a landmark node near the Crescent / Oldfield Road intersection; it synthesizes the existing improvements and brings the meadow to the city. The bridge is a timber-clad pathway wrapped in a lattice shell tunnel that varies in section, planted at the meadow side with Virginia Creeper. Over time, much of the bridge will become grown over, creating a dramatic transition from the Meadow to the city. Elongating and curving the bridge creates a definable place along the Crescent, and allows the bridge to meet the Meadow without mounding.
The lattice shell is a compelling visual sight from the intersection of Oldfield Road, and the structure literally envelops the passersby as they move along the pavement. The bus stop and Old Pint Pot stair entrance are integrated into the new Meadows bridge entrance. The existing pergola and bus shelter are replaced with a single element – a grand enclosure that invites discovery. The captivating structure is a key element of the Middlewood loop link.
The bridge bends toward the east, bringing the Crescent landing closer to the pedestrian crossing at Oldfield Road, and pulling pedestrian traffic into the Meadow. The distinct paving pattern at the intersection continues to the mouth of the new bridge.
The timber-clad walking path ‘floats’ within the lattice tunnel, making the walk through the bridge a spatial experience. The voluminous passageway varies in diameter, creating a variety of experience through movement. Vines growing on the shell change color with the seasons, adding another dimension to the walk.
The curved bridge gently slopes from the Crescent to the Meadow at a DDA compliant incline. Elongating and curving the bridge preserves the topography of the Meadow with an at-grade landing. The lower mouth of the bridge peeks through the trees bordering the Meadow, burrow-like, a modest but identifiable presence at the meadow’s edge.

英国索尔福德芳草大桥
这是由洛杉矶的Standard Architecture公司公布的英国索尔福德芳草大桥设计方案。位于新月奥菲尔德路旁。这座木材包就的人行天桥拥有一个网状的外壳隧道，建筑师们将植物栽种其上，随着季节的变化，植物绽放出不同的样貌，从市中心的景观，自然的过渡。
该人行桥将会取代现有的公车候车亭，为了使过渡更加平滑，建筑师们采取相同的铺装方式，延续到桥口。
建筑师的想象力还是很强大的 美感十足，蛮不错的！ 各种形式的异种桥梁，看上去非常不错！！ 下雨天不错，水帘洞 这个不仅需要很丰富的想象力，还需要有深厚的结构功底，如果要实现这些艺术品，并非一件易事！
