Glass Bridge, Huangchuan Three Gorges Scenic Area – a “transparent corridor” in the air

황추안 삼협 유리대교     교량은 지형을 기반으로 지어진 일종의 구조물로, 연결과 소통을 상징하는 예술의 일종이기도 하다. 광둥 성 롄저우에 위치한 저장대 건축디자인연구소(UAD)가 조성한 황추안 삼협 유리대교가 지역 랜드마크로 자리 잡으면서 자연환경에서 '성장'하는 듯하다. 구조물을 자연환경에 융합하고 혁신적인 건축방법을 배치함으로써 디자인팀은 자연과 인공의 매끄러운 통합을 실현했다. 구조물과 공간의 조화 '링난 지역의 그림 복도'로 알려진 황추안 삼협은 진주강 유역의 베이장강 계통과 장한고대길 종단의 주요 지류다. 당나라의 유명한 시인 한유는 그 웅장한 경치를 묘사하는 시를 쓴 적이 있다. 매달려 있는 유리다리는 절벽에 걸쳐 있으며, 북광둥에서 가장 큰 폭포 군락을 내려다보고 있다. 하늘로 솟구치는 용처럼 자연과 조화롭게 공존한다. 이 다리는 가시 투과율이 99.15%인 4.5센티미터 두께의 초고정밀 적층유리 3개 층으로 되어있다. 유리창은 수정 같은 광택과 높은 투명도, 굴절률로 교량 데크를 지탱한다. 유리와 곡선 스테인리스 철봉으로 구성된 가드레일, 브릿지탑과 붉은 주케이블이 어우러져 구조물과 공허함, 현대와 고전적인 것이 어우러진 축조된 풍경을 이룬다 황기철 콘페이퍼 에디터 Ki Chul Hwang Conpaper editor curator

Bridge is a kind of structure built based on the terrain, and also a sort of art that symbolizes connection and communication. Located in Lianzhou, Guangdong Province, the Glass Bridge in Huangchuan Three Gorges Scenic Area created by Architectural Design & Research Institute of Zhejiang University Co., Ltd. (UAD) becomes a local landmark, which seems to “grow” from the natural environment. Through blending the structure into the natural surroundings and deploying innovative construction methods, the design team realized the seamless integration of nature and the artificial.

Combination of the solid and void

Known as the “picturesque corridor in Lingnan region”, Huangchuan Three Gorges is the main tributary of the Beijiang River system in the Pearl River Basin and the end of Qianghan Ancient Path. Han Yu, a famous poet in Tang Dynasty, once wrote a poem to depict its magnificent scenery. The suspended glass bridge spans the cliffs, and overlooks the largest cluster of waterfalls in Northern Guangdong. Like a dragon that soars into the sky, it harmoniously coexists with nature.

The bridge is paved with three layers of 4.5-centimerter-thick ultra-clear tempered laminated glass, the visible transmittance of which is 99.15%. The glazing endows the bridge deck with crystal-like luster, high transparency and refractive index. The glass, the guardrails composed of curved stainless steel bars, the bridge tower and red main cables, together form a built landscape that combines the solid and void, the modern and the classical.

Responding to site conditions

Located in the southeast of China, Guangdong is affected by frequent typhoons in summer. Besides, due to the large span and flexible structural system, this suspension bridge requires excellent wind resistance performance. Based on those considerations, the design team carried out wind tunnel testing and finite elements simulation, analyzed the main frequency and modes of vibration, and identified design parameters such as critical flutter velocity and the reasonable degree of enclosedness of guardrails, which provided strong support for optimizing the design and the maintenance of the bridge in the future.

Meanwhile, in order to enhance lateral sustainability and wind resistance performance of the bridge, the designers adopted an oblique wind-resistant cable system, which is fixed to concrete anchors. Moreover, considering the adverse influences that karstification and special residual silty clay exerted on the site, they tried the best to ensure the safety performance of the bridge during design and construction phases.

An innovative built landscape

This glass bridge is suspended at a height of 201 meters, with a width of 8.8 meters. Spanning a length of 526.14 meters, it has broken the Guinness World Records as the world’s longest suspension glass bridge. Its completion is a miracle. So far, it has become a new local landmark, and has been attracting a large number of tourists and helping inject vitality into local tourism industry.

Based on respect to the land and nature, clear planning and positioning, creativity, and the courage to push the limits, UAD team reactivated the natural environment and produced an innovative built landscape that contributes to economic development. Creating built landscapes that integrate nature, city and culture has always been a focus of UAD’s design researches and practices.
