该桥连接了位于同名城市尼特拉河两岸的行人和自行车道。由于当地的限制,需要采用非常细长的桥面结构。此外,任何承重构件,如铁塔和电缆,位于人行道之外都是不允许的。因此,我们选择了一种经济的系杆拱桥结构,它代表了一种最合理的解决方案。为了使城市历史中心的景色不受干扰,拱门的高度尽可能的小。为了开放空间并邀请人们使用这座桥,桥面被悬挂在向外倾斜的拱肋上。这样一来,河桥就有了一个现代的、动态的外观。

The bridge connects pedestrian and cyclist trails situated along both banks of the River Nitra in a city of the same name. Due to local constraints the bridge structure with a very slender deck was required. Also, any load bearing members, such as pylons and cables, situated beyond the sidewalks were not allowed. Therefore, an economical tied arch structure, which represents a most logical solution, has been chosen. To allow an un-disturbing view of a historic centre of the city, the rise of the arches is as small as possible. To open the space and to invite using the bridge, the deck is suspended on outwards inclined arch ribs. In this way the river bridging received a modern, dynamic appearance.

桥面呈波峰曲线,最大纵向坡度为5.0%。由于桥面与由微型桩支撑的端部基座固定连接,该结构形成了一个整体结构系统。桥面由两根钢边梁组成,由地梁和预制混凝土板件加劲,其边缘悬挂在梯形箱形截面的钢拱肋上。为了避免混凝土桥面出现裂缝,该结构通过位于边梁箱体内的预应力钢索进行纵向后张。

The bridge deck is in a crest curve with a maximum longitudinal slope of 5.0%. The span length is 49.50 m, the free width between the railings is 4.00 m. Since the bridge deck is fixed connected with the end abutments supported by micro-piles, the structure forms an integral structural system. The deck, which is composed of two steel edge girders stiffened by floor beams and precast concrete slab members, is on its edges suspended on steel arch ribs of trapezoidal box sections. To avoid cracks in the concrete deck, the structure is longitudinally post-tensioned by prestressing cables situated in the boxes of the edge girders.

为了消除河床上的架设塔,由边梁和地梁组成的钢甲板通过位于边梁下的拉杆进行临时加固。桥面架设完毕后,钢拱架被放置,预制板构件被架设。当构件之间的连接处被浇注和预应力后,桥面被悬挂在拱肋上。桥梁的功能通过静态和动态负载试验得到了验证。

To eliminate the erection towers in the riverbed, the steel deck assembled of edge girders and floor beams was temporary stiffened by ties situated under the edge girders. After the deck was erected, the steel arches were placed and precast slab members were erected. When the joints between the members were cast and prestressed, the deck was suspended on the arch ribs. The function of the bridge was verified by static and dynamic loading tests.

钢结构被涂成白色,行走的表面被位于扶手上的LED灯照亮。拱门和边梁都由位于其底部翼缘的LED灯照亮。

The steel structure is painted white, the walking surface is illuminated by LED lights situated in the hand rails. Both, the arches and edge girders are illuminated by LED lights situated at their bottom flanges.
