竞赛二等奖 Second Prize

 

- 项目基地位于浦东新区沪南路与规划御南路交叉口，横跨南上海主要干道之一的十车道沪南路。基地现状西侧为商贸服务区域，东侧则为御康医院以及大片居民区。基地北侧不远处为现状公交车站。由于沪南路是十车道主干道，车流量大，行人换乘、穿行时，必定会影响交通效率。新的人行桥不仅联结了沪南路东西两侧的商贸服务区域和居住区，更释放了沪南路交通压力，提升了交通效率。

- 通过对场地周边现状的分析和对区域未来规划的分析，我们得出主要适用人群有，学生，换乘人群，上班族，购物人群，以及附近居民。通过对各类人群的使用需求分析，我们认为人行桥需要满足三大主要功能：快速通过，短暂停留，休憩休闲。

- 人行桥各方位的城市功能非常丰富，人群构成也比较复杂，通过对于各方位人流来源的分析，我们希望这不仅仅是一座人行桥，更是联系东西的城市纽带，是融入环境的街区风景，是激发地区活力的助推动力，更是展望未来的区域名片。

- 为此，我们对于东晖桥的愿景是，成为沟通未来与现在的未来之翼。

- 对于人行桥的结构选型，我们考虑到为保证桥下净空4.5米，加上钢箱梁的结构高度，人行使用面高度提高了，人行桥两侧的梯道需要更多梯步，占用的土地面积更大，对于现状复杂的用地条件不甚理想。

- 使用桁架结构形式同样可以解决大跨度的结构需求，也很容易保证净空4.5m，但是桁架结构的“存在感”较强，且自带较为强烈的“工业感”，使得对于环境的融入加重了难度。

- 最终，我们选择将桁架置于顶端，将人行部分楼板通过金属悬索吊起。桁架梁通过两侧的梁柱结构支撑，并在端点处通过配重下拉进行受力平衡。这样，我们既保证了净空高度，也解决了大跨度，同时在视觉上使得整个设计更加轻盈、现代、简洁。

- 东晖桥由两条桁架主梁吊起，桥面荷载通过钢索结构构件均匀的传递到两条主梁之上，再传递至两侧的钢筋混凝土结构之上，最后再由两段末尾的配重及内部钢结构提供下拉力，达到受力平衡。 

- 干净、整洁的市政环境，生态、绿色的环境体验，美观、现代的街区风景，人与城市和自然的联结沟通，充满朝气与温度的昂扬姿态，我们希望东晖桥成为区域新名片，努力呈现新时代、新发展下的区域新风采。

 

- The project site is located at the intersection of Hunan Road and planned Yunan Road in Pudong New Area, spanning Hunan Road, a major ten-lane thoroughfare in South Shanghai. The west side features a commercial service area, while the east side includes Yukan Hospital and a large residential neighborhood. A bus station is nearby to the north. Given the heavy traffic on Hunan Road, pedestrian crossings affect traffic efficiency. The new pedestrian bridge will connect the commercial and residential areas while alleviating traffic pressure.

- After analyzing the existing conditions and future plans, we identified key user groups: students, transfer passengers, office workers, shoppers, and local residents. The bridge must support three main functions: rapid transit, short stops, and relaxation.

- We envision this bridge as not just a crossing but a vital link connecting east and west, integrating into the environment and enhancing the area's vitality.

- For Donghui Bridge, we aimed for a design that connects the future with the present. We chose a truss structure at the top, suspending the pedestrian deck with cables, allowing for a 4.5-meter clearance without needing excessive stair steps. This ensures a lightweight, modern appearance.

- Donghui Bridge features two main truss beams, with loads evenly distributed through steel cables to reinforced concrete structures on either side, balanced by counterweights.

- We hope that Donghui Bridge becomes a new symbol of the region, embodying the spirit and development of this new era through a clean, green environment and vibrant connections between people, the city, and nature.
