專案概況

宜賓實施“科教興國”戰略，在國家級的三江新區建科研中心，宜賓市科技館（建築面積2。8萬㎡），位於其西南角的龍頭山下、白砂堰畔，是新區門戶，更是面向世界的一個視窗。

Project overview。 Yibin implements the strategy of “revitalizing the country through science and education”， and builds a scientific research center in the national Sanjiang new area。 Yibin Science and Technology Museum （with a building area of 28000 m2） is located at the foot of Longtou mountain and the Bank of Baishayan in the southwest corner of the city。 It is not only the gateway of the new area but also a window to the world。

設計特點

四向內收：為增加城市開放空間，建築四向居中內收，形成南側環抱的入口廣場，西側的大巴落客區，北側的貨運場地，東側的下沉廣場。

Design features。 Four sides adduction： In order to increase the open space of the city， the buildings are built in four directions， which form the entrance square surrounded by the south， the bus drop off area in the west， the freight yard in the north， and the sunken square in the East。

壓低抬高：為控制建築體量和造價，將部分功能半埋於地下。於是主入口地坪高出南側科技大道1。5米，正好以5%的緩坡銜接，彰顯氣勢。

Down and up： In order to control the volume and cost of the building， some functions are semi-buried underground。 Therefore， the main entrance floor is 1。5 meters higher than the South Science and technology Avenue， which is just connected by a gentle slope of 5%。

四翼上揚：為與山水相融，消隱樓層感，四翼懸挑上揚，象徵科技騰飛，和起伏山勢呼應，並形成室內跨層動線：沿邊庭拾級而上，至端部露臺，順勢入二層展廳，可觀可遊可憩。

Four wings up： In order to blend with the landscape and eliminate the sense of floor， the four wings are overhanging and rising， symbolizing the rapid development of science and technology， echoing the undulating mountains， and forming an indoor cross floor moving line： climb up the steps along with the side court， go to the end terrace， and enter the second-floor exhibition hall， where you can have a good view and rest。

藍綠黑白：建築立面上部為白色鋁板，基座為黑色石材，黑白對比，既符合科技館特點，又能與周邊藍綠環境相融。

Blue， green， black， and white： The upper part of the building facade is a white aluminum plate， and the base is black stone。 The black-and-white contrast not only conforms to the characteristics of the science and Technology Museum but also blends with the surrounding blue-green environment。

外挑下掛：南側邊庭外挑達10餘米，透過外側中距720的雙鋼柱懸掛在屋頂鋼架下，雙鋼柱兼做豎明橫隱玻璃幕牆的豎龍骨，以此實現懸浮通透的立面。

Overhanging and hanging down： On the south side of the court， the overhanging is more than 10 meters， which is suspended under the steel frame of the roof through the double steel columns with an outer middle distance of 720。 The double steel columns are also used as the vertical keel of the vertical exposed and horizontal concealed glass curtain wall， so as to realize the suspended and transparent facade。

室外疏散：為確保展廳的整體連續性，將多部疏散樓梯貼北側外牆佈置，其外觀沿用南立面玻璃幕的寬窄節奏，並創造性地取消窄玻璃，使其成為室外疏散樓梯。

Outdoor evacuation： In order to ensure the overall continuity of the exhibition hall， a number of evacuation stairs are arranged close to the North external wall。 The appearance follows the width and narrow rhythm of the south facade glass curtain， and the narrow glass is creatively canceled to make it an outdoor evacuation staircase。

曲面坡頂：屋面裝置較多，結合機房等的高低變化，第五立面採用穿孔鋁板形成和緩的曲面坡頂。

Curved slope top： There is much roof equipment， combined with the height change of the machine room， the fifth facade uses a perforated aluminum plate to form a gently curved slope top。
