架构师提供的文本描述。尼梅根市在一份文件中制定了这座桥的规格，概述了他们的雄心。在此范围内，制定了设计标准，帮助制定了项目。

Text description provided by the architects. The city of Nijmegen formulated the specification of the bridge in a document outlining their ambitions. Within this, design criteria were laid down which helped to set out the project.

第一个问题涉及环境内的安置问题。城市桥梁必须是河景不可分割的一部分，从河岸和桥梁本身都可以看到和体验。第二个标准要求该设计在重新安置堤坝和瓦勒河周围的空间发展方面与Nijmegen的现有和未来形象相一致。

A first issue concerns the placement within the surroundings. The urban bridge has to form an integral part of the riverscape, and be both seen and experienced from the banks as well as from the bridge itself. A second criterion requires the design to be consistent with the existing and future image of Nijmegen in terms of the relocation of the dyke and the spatial developments around the Waal River.

这意味着，作为主要交通基础设施，主要建筑必须与整个方案和功能相联系，并以理想的方式发挥作用。第三个雄心将这座桥描述为一件艺术作品，用一个手势来表达当代技术和设计。第四个标准侧重于桥梁的功能和经验价值：城市桥梁应该在桥面和地面创造一个“城市广场”，并在下面创造一个宜人的环境。

This means that the main construction has to stand in relationship to the whole programme and function in an ideal way as a major piece of traffic infrastructure. A third ambition describes the bridge as a work of art that, in a single gesture, articulates contemporary technology and design. The fourth criterion focuses on the function and experiential value of the bridge: the urban bridge should create an ‘urban plaza’, both on deck and at ground level, as well as a pleasant environment underneath.

Integral approach

这个设计为所有这些问题提供了不止一个答案。我们的设计文化的根源体现在稳定的物理规律和建筑工艺上，也体现在景观、地形条件、城市及其历史上：传统和文化形成了一个起点。我们的设计方法从“事物的本质”开始。我们利用在项目非常广泛的范围内可以找到的有价值的元素。

The design provides more than one answer to all of these questions. The roots of our design culture are reflected in the physical laws of stability and in construction craftmanship, but also in the landscape, the topographical conditions, the city and its history: the traditions and the culture of a place form a starting point. Our design approach starts from ‘the nature of things’. We utilise the valuable elements that can be found within the very broad context of the project.

此外，经济和组织财务流程、决策程序和规章，按照自己的逻辑和制度运作：今天，这需要规划，并纳入复杂的建设项目。这就是我们对整体方法的理解，通过这样的方式，我们相信我们的项目会产生不可预测的附加价值，与现有环境相区别，并在此基础上启动其他转变。

In addition, the economics and the organisation of financial processes, decision-making procedures and regulations, operate according to their own logic and systems: today, this needs to be planned and incorporated into complex construction projects. This is what we understand by the integral approach. By proceeding in this way, we are confident that our projects generate unpredictable added value, differentiate themselves from the existing surroundings and, on top of that, set other transformations in motion.

 Floor Plan

综合办法还意味着，所有有关各方，从不同的学科和职能，都应对这一挑战。有永久的沟通：这是不分等级的，基于这样的信念：在处理现代复杂事物时，这是必不可少的。

An integral approach also means that all the parties involved, from various disciplines and functions, rise to the challenge. There is permanent communication: this is non-hierarchical and based on the belief that this is essential when dealing with modern day complexities.

桥梁设计

Design of the bridge

这座桥的设计是一个舞台。这是对瓦尔河、洪泛区和两条堤坝雄伟性质的戏剧性反应。城市桥梁给景观带来了结构、层次和方向。拱门，这是主要的特征，既确认和跨越河流。与横跨水面的纯功能跨度不同，拱门尊重河流的宽度，因此认可了河岸的位置。即使在冬天，当水位更高，洪水漫过时，拱门仍然令人信服地证明了瓦尔河的位置和身份。

The design of the bridge is a staging. It is a theatrical response to the majestic nature of the Waal River, the floodplain and the two embankments. The urban bridge brings structure, hierarchy and orientation to the landscape. The arch, which is the main feature, both confirms and spans the river. Unlike a purely functional span across the water, the arch respects the width of the river and thus endorses the location of its banks. Even in winter, when the water levels are higher and the floodplain overruns, the arch remains convincing proof of the location and identity of the Waal.

桥梁的设计是基于一种结构逻辑，它以几何由作用力决定的原则为出发点。我们选择形式不是为了他们自己，而是用力量来发展一种形状。因此，力成为一种设计工具。一旦基本几何可以固定，这种形式的‘构图’或物化可以被调查。对一座新桥的需求提供了机会，创造了一座21世纪的拱桥，这是西方文化的当代象征。“瓦勒大桥”作为当时的“纪念碑”，在正式和工程上的雄心方面，提出了更高的期望。

The design of the bridge is based on a structural logic that takes, as its starting point, the principle that the geometry is determined by the forces at work. We do not choose forms for their own sake, but use the forces to develop a shape. The forces thus become a design tool. Once the basic geometry can be fixed, the ‘composition’ or materialization of this form can be investigated. The need for a new bridge provided the opportunity to create a 21st century arch bridge, a contemporary icon of Western culture. The Waal Bridge as a counterpart and ‘monument of its time’ raises expectations even higher in terms of formal and engineering ambitions.

‘de Oversteek’的坡道是由一系列与自然有关的材料和建筑方法设计的。它涉及到传统的技术(现场浇筑混凝土和砖石)，创造了一种手工艺的感觉。与拱桥不同的是，坡道的设计、材料、尺寸和细节都是从人的角度来阐述的。这座新桥梁的设计采用了整体的方法，结合了当代对总体规划、施工技术和概念设计的知识。

The ramps of ‘De Oversteek’ are designed from a range of materials and construction methods that relate to nature. It involves traditional techniques (cast in situ concrete and brick masonry) that create a feeling of craftsmanship. The design, materials, dimensions and detailing of the ramps, unlike the arch bridge, are elaborated on a human scale. The new bridge is designed with an integral approach, using a combination of contemporary knowledge on master planning, construction techniques and conceptual design.

这座桥是一个经过深思熟虑的优化过程的结果，它将工程、城市化和建筑结合起来。设计过程的一个主要目的是使结构的效率得以体现。没有附加的“伪造”。这座桥与物理定律是一致的和合乎逻辑的。自然美是一种结果。拱桥的主跨为285 m，拱桥的总长度为1，2 km。

The bridge is the result of a well thought-out process of optimisation combining engineering with urbanism and architecture. A principle aim of the design process is to make the structural efficiency visible. There are no added ‘counterfeits’. The bridge is coherent and logical in relation to physical laws. Natural beauty is a consequence. The main span of the arch bridge is 285m long; the total length of the structure, the arched bridge including the approach ramps, is 1,2 km.
