Renzo Piano’s Genoa San Giorgio Bridge, which is the replacement for the Morandi Bridge that collapsed in a storm almost two years ago, has opened in Italy.
Built in Piano’s home town of Genoa, the 1,100-metre-long motorway bridge was inaugurated by the Italian prime minister almost exactly two years after the previous bridge collapsed on 14 August 2018 killing 43 people.
倫佐·皮亞諾（Renzo Piano）的熱那亞聖喬治橋（Genoa San Giorgio Bridge）已在意大利開幕，該橋是莫蘭迪橋（Morandi Bridge）的替代品，該橋在兩年前因暴風雨而倒塌。
這座長達1100米的高速公路大橋建於皮亞諾的家鄉熱那亞，在2018年8月14日前一座橋倒塌近兩年後，由意大利總理揭幕。
The design and build of the new bridge over the Polcevera river and the area of Val Polcevera was completed in less than two years following round the clock construction.
“Its rapid reconstruction aims to become a model for the renovation and adaptation of Italian infrastructure with a high social, economic and strategic significance,” said Piano’s studio Renzo Piano Building Workshop.
全天候建設，不到兩年的時間便完成了新的橫跨Polcevera河和Val Polcevera地區的橋樑的設計和建造。
皮亞諾的工作室倫佐·皮亞諾建築工作室說：“其快速重建旨在成為具有重大社會，經濟和戰略意義的意大利基礎設施翻新和改建的典範。”
Described by the studio as an “urban bridge”, the bridge’s deck is supported by 18 slender reinforced concrete piers spaced 50 metres apart except in the central section where they are separated by 100 metres.
Each of the piers has an elliptical section designed to allow the light to “slip” on the surface and help mitigate the impact on the neighbourhood below.
工作室將其描述為“城市橋樑”，該橋的甲板由18個細長的鋼筋混凝土墩支撐，這些墩間隔50米，中間的部分相距100米。
每個墩都有一個橢圓形的截面，旨在使光線在表面上“滑動”，並有助於減輕對下方鄰域的影響。
The piers support a steel and concrete deck that is isolated by a system of support devices that are designed to protect the structure from seismic activity.
According to Piano’s studio, the underside of the deck is curved to be reminiscent of the form of a ship.
橋墩支撐著由混凝土支撐設備系統隔離的鋼和混凝土甲板，這些支撐設備旨在保護結構免受地震影響。
據皮亞諾（Piano）的工作室稱，甲板的下側是彎曲的，讓人聯想到船的形狀。
“From an architectural point of view, the form described by the deck, which recalls the hull of a ship, is of great importance,” said the studio.
“The gradual reduction of the section towards the ends of the bridge attenuates the visual impact of the new infrastructure. In addition, the use of a light colour for the coating of the steel elements makes the bridge bright, harmonising its presence in the landscape.”
該工作室說：“從建築的角度來看，甲板所描述的形狀非常重要，它能使人聯想起船體。”
他說：“逐漸縮小到橋樑末端的截面，減弱了新基礎設施的視覺衝擊。此外，在鋼構件的塗層中使用淺色使橋樑更加明亮，從而協調了其在景觀中的存在。 ”
Along the sides of the bridge deck are a series of metal fins that extend from the bridge’s steel structure along with rows of photovoltaic panels that will power its lighting and a 2.5-metre-high protective glass barrier.
“The transparency of the glass and, consequently, the extreme visual permeability that derives from it, makes it possible to observe the surrounding landscape by crossing the new bridge, as well as lightening its presence in the valley for those who will live it from the city,” said the studio.
沿著橋面板的側面，有一系列金屬鰭片，從橋的鋼結構延伸出來，還有成排的光伏板（將為照明提供動力）和2.5米高的保護性玻璃屏障。
“玻璃的透明性，以及由此產生的極高的視覺通透性，使人們有可能通過越過新橋來觀察周圍的風景，並減輕那些會從玻璃中居住的人在山谷中的視線。 城市。”工作室說。
Described as an “intelligent instrument” by the studio the bridge will be continuously monitored using a system of internal sensors including accelerometers, extensometers, velocimeters, inclinometers and detectors for joint expansion.
These sensors will be supplemented by robots that will run along rails on the bridge’s edge to monitor the superstructure externally and will also clean the photovoltaic panels.
工作室將橋形容為“智能儀器”，將使用內部傳感器系統（包括加速度計，引伸計，速度計，傾角計和聯合伸縮檢測器）對橋樑進行連續監控。
這些傳感器將由機器人進行補充，這些機器人將沿著橋邊緣的軌道運行，以從外部監控上部結構，並清潔光伏面板。
The Genoa San Giorgio Bridge replaces the Morandi Bridge, which was completed in 1974 and was a local landmark in the city of Genoa.
Designed by Italian engineer Riccardo Morandi, the cable-stayed bridge was completed in 1967 and had an unusual structure as it was a concrete cable-stayed bridge.
As part of the plan to rejuvenate of the area under the collapsed bridge, Stefano Boeri has designed elevated walkway as part of the Polcevera Park and The Red Circle masterplan.

熱那亞聖喬治橋取代了莫蘭迪橋，該橋於1974年完工，是熱那亞市的當地地標。
斜拉橋由意大利工程師里卡多·莫蘭迪（Riccardo Morandi）設計，於1967年完工，由於它是混凝土斜拉橋而具有不尋常的結構。
作為振興倒塌橋下區域的計劃的一部分，Stefano Boeri設計了高架人行道，作為Polcevera公園和Red Circle總體規劃的一部分。
