这座位于城市休闲区的人行天桥,连接着河的左岸和Bölesholmarna岛,并与一座连接河臂的小桥相连。人行桥连接着位于河两岸的行人和自行车道;它还承载着电力和通信电缆。

The footbridge, which is situated in the city’s recreation area, connects the river’s left bank with the island of Bölesholmarna and links up to a small bridge bridging the arm of the river. The footbridge connects pedestrian and cyclist trails situated along both river’s banks; it also carries electrical and communication cables.

人行桥由一跨长度为179.00米的预应力混凝土桥面组成,它被悬挂在两根倾斜的悬索上,三跨长度分别为28.80+187.00+29.50米。桥面由59个三米长的预制混凝土段和两个整体的端部横梁组装而成,电缆的最大下垂为20.90米。

The footbridge consists of a prestressed concrete deck of one span of the length of 179.00 m, which is suspended on two inclined suspension cables of three spans of lengths of 28.80+187.00+29.50 m. The bridge deck has a variable width – from 6.40 m in the middle of the bridge to 8.40 m at the abutments. The maximum sag of the cables is 20.90 m. The bridge deck is assembled of 59 three-meter-long prefabricated concrete segments and two monolithic end cross members.

桥面的流线型截面仅由400毫米深的边梁和140毫米厚的桥面板组成。每个分段在连接处都有地梁加固。两根悬索由2×55个单股组成,灌注在直径273毫米的钢管中。桥面与桥中间的悬索固定连接。

The streamlined cross-section of the bridge deck consists of only 400 mm deep edge beams and a 140 mm thick bridge deck slab. Each segment is reinforced by floor beams at the joints. Two suspension cables consist of 2×55 mono-strands grouted in steel pipes of 273 mm diameter. The deck is fix connected with suspension cables in the middle of the bridge.

30.25米高的铁塔呈字母A的形状。铁塔的腿是纵向和横向倾斜的,由预制的、匹配的混凝土段组装而成。在铁塔的顶部,电缆的锚箱被连接到腿上。缆绳的拉力被传递到锚定在基脚板上的末端钢锚块上。

The 30.25 m tall pylons have the shape of the letter A. The pylons’ legs, which are inclined longitudinally and transversely, are assembled from precast, match-cast concrete segments. At the pylons’ tops, anchor boxes of the cables were connected to the legs. The tensile force from the cables is transmitted to the end steel anchor blocks anchored in the footing slabs.

在桥墩上,桥面由多方向的支座支撑;伸缩运动的纵向引导由位于桥梁轴线上的引导支座来保证。为了减少桥面因活荷载和风荷载的动态成分而产生的纵向运动,桥面由2×2的冲击过渡单元与基台连接。这些单元,加上悬索与桥面在中跨的固定连接,保证了桥梁的空气动力学稳定性。

At the abutments the deck is supported by multi-directional bearings; the longitudinal guidance of expansion movements is ensured by guide bearings located in the bridge axis. To reduce the deck’s longitudinal movement due to the live load and dynamic component of the wind load, the deck is connected with the abutments by 2×2 shock-transition units. These units, together with the fixed connection of the suspension cables with the deck at the mid-span guarantee the bridge’s aerodynamic stability.

一个简单的栏杆,是由倾斜的柱子支撑的扶手形成的,有绳索填充。走道由位于扶手上的LED灯照明。

A simple railing, which is formed by a handrail supported by inclined posts, has rope filling. The walkway is lit by LED lights situated in the handrails.

利用悬挂式结构系统可以设计出一个细长而透明的结构,其规模与环境相一致,其形状与没有直线的美丽乡村相匹配。该结构是轻盈和透明的;它由具有人类尺度的元素组成。该结构没有克服美丽的环境,而是对其进行补充。这座桥对使用者来说是舒适的,它的运动由行走的人或风引起,不会给使用者带来不愉快的感觉。

Utilizing the suspension structural system allowed the designing of a slender and transparent structure whose scale corresponds to the setting and whose shape matches the beautiful countryside where there is no straight line. The structure is light and transparent; it consists of elements that have a human scale. The structure does not overcome the beautiful surroundings, but it complements them. The bridge is comfortable for the users, and its movement caused by walking people or wind does not cause unpleasant feelings to users.
