台湾--王公渔港景观桥工程设计案例

参展说明

The Wang-Gong Footbridge is located near the Wang-Gong fishing port, across Hou-Gang River, and connects the port and street block areas. The Zhang-hua County Government plans to transform Wang-Gong fishing port into a multi-function port; therefore, other than just a connection, this bridge will serve as a site for sightseeing, leisure, and ecological education, and a new landmark in the port area.

Form of Bridge, Structural Materials and Micro-Climate

Using steel trusses and folding panels, the design takes the form of an intelligent bridge, appearing like a sculpture between two sea dikes. The main structure bears the load with steel truss arches, and fiber cement panels are used as cladding system.

The bridge is located at the meeting ground between sea and land; sea and land wind change remarkably between day and night, and at times strong wind can make walking difficult; furthermore, sunshine in the open area of the polder land can be very uncomfortable. Besides posing as sculptural forms, the dynamic folding panels also extend into different directions and act as sunshades, windshades and railings, considerately meeting the demands of scenery enjoyment.

Cladding Materials

Due to its seaside location, the materials and surface finishing must be made salt-resistant and wind-resistant. The body of the bridge is first cladded in high-density fiber-cement panels, then finished with heat-resistant, self-cleaning exterior wall paint, thus forming a seamless layer that protects the structure from salt damages.

Colors and Lighting

The body of the bridge takes a grayish blue color as its theme, in order to blend in with the coastal scenery - the gray and white of the sea dikes, the deep blue of the river, the sky, and the ocean.

Scenery Viewing and Ecology Guidance Facilities

The folding panels on the bridge changes according to the line of traffic and forms spaces for seating, viewing spots, and guide panels; they draw people to stay and enjoy the scenery, which includes the tidal changes and sunset at the marine outfall of Hou-Gang River, and the tidal zone ecology nearby.

王功生態景觀橋靠近王功漁港，橫跨後港溪，連結港區及街區。由於彰化縣政府計畫將王功漁港轉型為多功能漁港，因此這座橋除了連結的功能之外，還將發揮觀景、遊憩及生態教育的功能，並成為港區的新地標。

橋樑形式、構造材料與微氣候

運用桁架與折板結合成一俐落橋型，在兩道海堤中如一輕巧雕塑。主結構以鋼構桁架拱的形態來傳遞力量，並以高密度纖維水泥板為主要包覆材料。

橋樑地處海陸交界，晝夜之間海陸風的變換顯著，風勢強勁時會使人行動困難，海埔地的空曠地形也使陽光照射讓人難耐。動態的折板除了創造出雕塑般的形態，也在各個向度延展成為遮陽、擋風及扶手設施，妥善照顧到觀景的需求。

包覆材料

由於位在海邊，材料及表面塗裝必須考慮抗鹽蝕及耐風化。橋身以高密度纖維水泥板完成外殼包覆後，再塗裝能隔熱自潔的外牆塗料系統，形成無縫隙的保護層，確保構材不受鹽份侵蝕。

色彩及照明

橋體順應灰白色的海堤、深藍色的河流及廣大的天空與海洋景觀，以能相容於海岸景觀的灰藍色調為主。

因應高度日照的地域特性，設置了容量1千瓦到1.5千瓦的太陽能發電板，提供照明所需的能源。

觀景及生態解說設施

隨著動線變化的折板，於橋面上適時地形成座位、觀景台或解說板等空間，使人們能夠停留觀景，除可遠眺後港溪出海口的潮夕變化及夕照，亦可就近觀賞潮間帶的濕地生態。

张永和评论

这里台北建筑师廖伟立设计的是一座桥又不止是一座桥，它还是街道，景点，地标，以及休息和进行生态教育的场所。桥的多种用途说明它是一座建筑，它的设计自然由建筑师来担任。
