Scenic Architecture Office-Bridge of Nine Terraces
Scenic Architecture Office는 남측에서 북측으로 낮아지는 경사를 따라 VOCO B&B호텔의 북서측면과 멜론밭의 북서측 코너에 위치한 창고 그리고 마을 북측의 전경이 내려다 보이는 보행자 다리를 제안한다.
보행자 다리는 원예 엑스포 마을과 북쪽의 점보 박물관을 연결하여 관광객들이 쉽게 오갈 수 있도록 한다. 장소와 장소를 연결하는 동선역활 뿐만 아니라 마을을 랜드마크로 이곳을 찾는 보행자에게 휴식을 제공한다.
The Horticultural Expo Village is located on the northern slope of Xian Mountain, which is in the northern part of the 11th Horticultural Expo Park, Nanjing. The terrain is high in the south and low in the north, where the Scenic Architecture Office designed the Northern Inn of VOCO B&B Hotel, a small shed in the northwest corner of the melon field, and a covered pedestrian bridge to the north of the village. This stretch of the Qixiang River flows along the northern foot of the Xian Mountain, and the east and west sides offer a great view of the valley in the direction of Baohua Mountain and Zhong Mountain. The pedestrian bridge connects The Horticultural Expo Village and the Jumbo Museum to the north of it, making it easy for guests to come and go. Crossing the river from the north to the south, the Bridge of Nine Terraces is a walking pathway into The village, with the Xian Mountain, Lian Mountain, and Yangshan Mine Pit unfolding in front of you behind the village. In addition to meeting the circulation needs, we hope to build a pedestrian bridge here as a resting place and a landmark to the north of the village, so that seeing the bridge gives people a feeling of "going home".
Among the existing types of bridges, a covered bridge is a kind of "slow" bridge, with a covered structure that provides space for viewing, resting, and even market activities. There are many examples of covered bridges all over the world, in southern China, Europe, and North America. Most of them rely on substructures to support the upper pavilions, such as the inter bearing wooden pole arch bridge in Taishun, the Ponte di Rialto stone arch bridge in Venice, and the Chapel Bridge supported by continuous piers in Lucerne, there are also bridges that combine of structure and space, such as the truss-like corridor bridge in Madison County. In Nanjing Horticultural Expo Village, we tried to explore the appropriate structural form for this bridge in terms of the surrounding landscape and visitors’ experience.
The barge of the Qixiang River is naturally sloped, and the width of the river varies between 18 and 30 meters due to the large difference in water level between the abundant and dry periods. This makes the structure span up to 37.8 meters on one hand, and on the other hand, the bridge deck elevation needs to be maintained above the high water level plus the safe height for boat traffic all the time. If the traditional arch bridge form is used, an arch height of at least 3 meters will make it difficult to get on and off the bridge, and will not solve the accessibility needs; if the single span ordinary box girder is used, the bottom structure thickness would reach nearly 2 meters, which is also not friendly to the walking experience, and will weaken the intimate scale of water viewing on the bridge during the dry period; if the thin rod arch or truss structure is used, the tall structural members will have a strong industrial feel, which will be hard to coordinate with The village’s landscape –After several common structural forms proved to be unsuitable, we once again found our way to the traditional dwelling form of the double-pitched roof.
