架构师提供的文本描述。这座为行人和骑自行车者修建的跨过萨文加的新桥，取代了一座位于河流上方的旧人行桥，给城市带来了持续的洪水风险。

Text description provided by the architects. The new bridge for pedestrians and cyclists across Savinja replaced a former footbridge which was placed low over the river and posed a constant risk of flooding for the city.

新行人天桥的位置位于中央图书馆左岸中央图书馆前的博物馆广场与萨文加河右岸城市公园的长廊之间的轴线上。在更广泛的背景下，人行桥将左岸的中世纪城镇中心与右岸的城镇公园连接起来。在右岸，现有的人行桥与沿着帕蒂赞斯卡街行驶的人行道和自行车道相连，在左岸与巴多文č伊娃街交叉，并连接到萨文加堤坝沿线的小径，穿过博物馆广场，进入全镇的人行道和自行车道系统。

The location of the new footbridge lies on the axis connecting the Museum square in front of the Central Library on the left bank, with the promenade in the town park on the right bank of the Savinja River. In a wider context the footbridge connects the medieval town center on the left bank with the town park on the right bank. On the right bank the existing footbridge connects to footpaths and bicycle paths running along Partizanska street, on the left bank it intersects Badovinčeva street and connects to the foot path along the Savinja embankment, and across the Museum square into the system of footpaths and bicycle paths throughout the town.

由于萨万加河沿线的防洪措施，有必要提高现有人行桥的水平，提高沿河防洪堤的水平，规划与城镇公园和帕蒂齐安斯卡街的行人路和自行车道连接的交叉口。这就是起点，代表了规划更换斯普拉沃斯卡BRV人行桥的背景。

Due to the flood protection measures along the Savinja River, it was necessary to raise the level of the existing footbridge, raise the level of the flood protection dikes along the river, carry out a planning intersection of the  footpath and bicycle path connection to the town park and the Partizanska street. Such were the starting points, representing the context for planning the replacement of the Splavarska brv footbridge.

新的结构补充了现有空间元素的图示。它保留了古镇全景的优雅，并提供了新旧文化对话。每一个时代都会在太空中留下一座新的桥梁。因此，对桥梁结构的选择及其建筑与象征形象的选择，旨在寻找尽可能薄的桥梁大跨度物体。这座桥是一跃跨过这条河。因此，这座新的行人天桥不会以奢华或华美的方式与城市风光的氛围竞争，而是会以年轻的优雅和大胆作为补充，而这些都是利用新技术和新知识来实现的。

The new construction complements the iconography of existing spatial elements. It preserves the grace of the old town panorama and offers a cultural dialogue between the old and the new. Each era leaves a mark in the space with a new bridge. Therefore the decision on the choice of the bridge construction and thus its architectural and symbolic image was aimed at finding a long span object with the bridge beam as thin as possible. The bridge was to span the river in one leap. The new footbridge therefore will not compete with the ambiance of the town scenery by being extravagant or garish, but will complement it with a youthful elegance and boldness, which are made possible by using new technologies and knowledge.

为厘米而战

BATTLE FOR CENTIMETERS

在设计符合上述基本房地的建筑计划时，我们遇到了三个看似不可调和的障碍。第一，海岸极低(高度不对称)，有必要允许直接进入大桥；第二，由于河流的洪水风险，需要更高的桥梁建设；第三，要求坡度最高为6%，也允许残疾人过桥。为了实现这些目标，我们发现了一种创新的建筑设计理念，桥的截面几何形状是可变的。

In designing the construction plans that would correspond to the above mentioned basic premises we encountered three seemingly irreconcilable obstacles. Firstly, the shores were extremely low (and of asymmetric heights) from which it was necessary to allow direct access to the bridge, secondly, the demand for a  greater height of the bridge contruction due to the flood risk of the river, and thirdly, the demand for a maximum 6% slope, allowing bridge crossing also to the disabled people. To achieve these goals we found an innovative construction design concept with a variable cross-sectional geometry of the bridge.

结果似乎很简单，但实际上是一个复杂而动态的空间形式，只有使用最新的技术和计算机辅助设计才能实现。它是一种视觉语言，间接地讲到了物体形成的时间。因此，这座桥被非物质化了，其元素的歌词柔和的线条和浅蓝色(Ral-7035)的选择，这进一步剥夺了它的构造质量。这样，它就变成了一个抽象概念，一个象征，一个新的城镇图标。浅色桥梁给人一种通风，阳光和轻盈的感觉。为了保存城镇的夜景，或者更确切地说，为了保持对星空的畅通无阻的看法，桥梁照明只能由隐藏在篱笆下的LED灯提供。唯一的例外是底部桥梁跨度的谨慎照明，其本身具有独特的形状，因此在城市夜景中也创造了一个可识别的形象。行人表面的设计类似于帆船甲板，略微拱形，并以栅栏保护不受河流影响，给人一种航海的感觉。

The result seems simple but is in fact a complex and dynamic spatial form, which can only be realized using up-to-date technology and computer-assisted designing. It is a visual language indirectly speaking about the time in which the object was built. The bridge is thus dematerialized with lyrically softened lines of its elements and the choice of light blue color (RAL-7035), which additionally takes away its tectonic quality. In this way it becomes an abstract idea, a symbol and a new icon of the town. Bridges in light colors give an airy, sunny and lightweight feel. In a desire to preserve the night panorama of the town, or rather, to retain an unobstructed view of the starry sky, the bridge lighting is provided only by LED lamps concealed under the fence ledge. The only exception being the discreet lighting of the bottom bridge span, itself of unique shape, thus creating a recognizable image also in the night panorama of the town. Pedestrian surface is designed similarly to a sailboat deck, slightly arched and protected from the river with a fence, giving it a nautical feel.

桥的几何形状

THE GEOMETRY OF THE BRIDGE

这座人行桥的形状是一条略微紧张的钢桥梁，横截面变化，从萨文加路堤延伸到深度较深的帕蒂兹安斯卡街，跨度为73米，跨距8米，向下延伸至26米高、24米宽的城镇公园水平。在纵向部分，钢梁的高度变化很大，从左岸河床上的70厘米上升到河中结构的顶部的1.64米，并且沿着帕蒂齐安斯卡街的支撑墙越来越薄，在那里它又达到了70厘米的高度。从那里，人行桥继续形成螺旋形，那里的梁只有30厘米高。最后给出了一个整体楔形的具体结论.桥梁截面(由厚钢板制成的箱体结构)呈梯形。上部为3.30cm，下部为3.30cm，宽度根据纵断面的特点而变化；桥冠为1.39m，螺旋为2.95m。由于所选择的截面几何形状，这座桥看起来比通常的梁结构要轻一些。

The footbridge is shaped as a slightly tense steel bridge beam with a varying cross section, which extends from Savinja embankment to the deepened Partizanska street in a single span of 73 meters, crosses the street in the span of 8 meters and lowers towards the level of town park in the shape of a spiral, which is 26 m high and 24 m wide. In the longitudinal section the steel beam has a varying height, rising from 70 cm at the bed on the left bank to 1.64 m at the crown of the structure in the middle of the river and is growing thinner towards the supporting walls along the Partizanska street, where it reaches the height of 70 cm again. From there the footbridge continues to the shape of the spiral, where the beam is only 30 cm high. At the end of the spiral a monolithic wedge-like concrete conclusion is made. The bridge beam cross section (a box structure made of thick steel sheets) is of trapezoid shape. It measures 3.30 cm on the upper side, while on the lower side its width varies depending on the characteristics of the longitudinal section and measures from 1.39 m at the crown of the bridge, to 2.95 m at the spiral. Due to the chosen geometry of cross sections the bridge will seem lighter than the usual beam constructions.

 Floor Plan

在左岸，桥梁被固定在深桩上的一个沉重的基础上，在右岸，它被固定在一个盒子形的AB框架中，由两堵支撑墙组成，沿着帕蒂齐安斯卡街，被放置在下面的混凝土板上，位于帕蒂齐安斯卡街下的考古层之上。公园内的桥头以螺旋形的形式，由薄的圆形钢柱节点支撑。

On the left bank the bridge is fastenedinto a heavy foundationon deep-seated piles, on the right bank it is fastened into a box-shaped AB frame, formed by two supporting walls along the Partizanska street and are placed on underlying concrete slab, lying above the found archeological level under the Partizanska street. Endingof the bridge in the park in the form of a spiral is supported by thin round steel columns joints.
