架构师提供的文本描述。简单如一笔，苗条的形式，克劳德伯纳德立交桥优雅跨越大道Périphérique之间的奥贝维利人和巴黎。这座近100米长的拱形木结构将密尔内尔公园与克劳德·伯纳德城市开发区连接起来，这是一个标志性遗址的化身。在这个瞬息万变的地区，法国东北部的发展政策，欧洲大厦和住宅建筑与电影院、疗养院、托儿所、学校、体育设施、多式交通枢纽(包括RER E快速公交线路、四条公共汽车路线)相提并论，以及电车系统上的3号和T8号路线)、一个公园和一个

Text description provided by the architects. Simple as a brushstroke, slender in form, the Claude Bernard overpass elegantly spans the boulevard Périphérique between Aubervilliers and Paris. This arched timber structure, nearly 100 metres in length, connects the Parc du Millénaire to the Claude Bernard urban development zone, the very embodiment of an emblematic site. In this rapidly-changing district, a agship for development policy in the north-east of the Ile-de-France, o ce blocks and residential buildings rub shoulders with a cinema, a nursing home, a nursery, a school, sports facilities, a multi-mode transport hub (incorporating the RER E rapid transit line, four bus routes, and routes 3 and T8 on the tram system), a park and a

购物中心这种发展的多样性要求采取新的方法来考虑城市密度、多功能和紧凑性，与巴黎城市气候行动计划的目标相一致的总体环境方针进一步强调了这一点。一种改变导致另一种改变：改变城市环形公路的地位，现在被认为是一条城市林荫大道。因此，这一挑战的规模在于通过提供立交桥来支持这一地方动态。这不仅仅是一个桥接结构，它还需要一个统一的和象征性的特征。这一简介已被DVVD建筑、设计和工程代理公司的建筑师完美地实现。

shopping centre. This developmental diversity has dictated a fresh approach to the consideration of urban density, multi-functionality and compactness, further accentuated by an overall environmental approach which is consistent with the objectives of the climate action plan of the City of Paris. One change leads to another: a change in the status of the city ring road, now conceived as an urban boulevard. The scale of this challenge was therefore to support this local dynamic through the provision of an overpass. More than just a bridging structure, this needed to be a unifying and symbolic feature. This brief has been perfectly realized by the architects at the DVVD architecture, design and engineering agency.

像立交桥这样的技术项目所涉及的约束条件不是一成不变的.例如，要求尽可能减少对trc车辆的干扰，规定了一种不寻常的安装程序：一旦桩式桥台及其相关楼梯安装到位，中央部分就会在一个晚上内全部安装在其永久支架上。这项艰巨的行动涉及部署一台容量极高、在欧洲几乎独一无二的移动式起重机。这台起重机位于Périphérique外林荫大道上，以创纪录的时间记录了增加其承载能力所需的众多衡重，完成了起重操作，然后消失，使trc得以在一个新的交叉结构下恢复。基于同样的优化思想，采用先进的数字工具实现了立交桥几何形状的连续化、无落差、金属框架结构的设计。目的是为了减轻结构，优化预算，节约原材料，方便提升操作。

A technical project such as an overpass involves constraints which are not run-of-the-mill. The requirement for the least possible disturbance to vehicle tra c, for example, dictated an unusual installation procedure: once the pile- mounted abutments with their associated stairways were in place on either side, the central section, fully- tted with its timber cladding and decking, was mounted on its permanent supports in a single night. This arduous operation involved the deployment of a mobile crane of exceptionally high capacity, of a virtually unique type in Europe. This crane was positioned on the outer Boulevard Périphérique,  tted in record time with the numerous counterweights required to increase its load-bearing capacity, completed the lifting operation, then disappeared, allowing tra c to resume under a new crossing structure. With the same idea of optimization in mind, the de nition of the geometry of the overpass as a continuous arch, with no drops, and the design of its metal framework structure have been executed using sophisticated digital tools. The objective was to lighten its structure, optimize the budget, economize on raw materials and facilitate the lifting operation.

2015年5月14日夜间起重作业的日程安排是由总承包商和项目承包商一分钟地计划的。该人行道的安装涉及同时关闭Périphérique内、外大道上的行车道三个小时-这一行动自开放以来从未进行过。这一精密工程项目是与巴黎市和该地区的服务部门合作构想的。

The scheduling of the night-time lifting operation, on 14th May 2015, was planned minute-by-minute by the prime contractor and the project contractors. The installation of the walkway involved the simultaneous closure of carriageways on the inner and outer Boulevard Périphérique for three hours – an operation which had never been undertaken since its opening. This precision-engineering project was conceived in partnership with the services of the City of Paris and the Prefecture.
