La Barra "wavy" Bridge
香格里拉巴拉”波浪”橋
La Barra Bridge, located in La Barra, Maldonado,
Uruguay, illustrated below,
was created by the engineer
Leonel Viera (1913-1975) to expand the area of Punta del Este.
This pioneered the construction sequence now typical
for concrete segment bridges of this type.
After placement of the principal cables,
precast concrete tiles were placed to form the initial structure.
The cables were then prestressed by loading sandbags upon the tiles,
followed by final concretization of the gaps between tiles.
Removal of the sandbags then compressively stressed the concrete structure,
enhancing its stiffness and durability under load.
An identical bridge was later constructed parallel to the first.
香格里拉巴拉大橋,位於烏拉圭,馬爾多納多,香格里拉巴拉,
如下圖所示是由工程師萊昂內爾•維埃拉(1913年至1975年)創建,
擴大埃斯特角城的區域。這開創了建設時序,
現在典型的這種類型的混凝土管片橋梁。主電纜的放置後,
預製混凝土瓦片放置以形成初始結構。
然後通過電纜裝載於所述磁磚沙袋,
隨後磁磚之間的間隙的具體化的最終預應力。
除去沙袋然後壓應力的混凝土結構,
在負載下提高其硬度和耐用性。
一個相同的橋後來構建到第一平行。
