It only needs to be designed to withstand the weight of the water! 公仔箱論壇: e, a% \4 s$ d0 @5 r# Y
Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loadedTVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。/ ], d) i4 E+ [ 3 p% i+ l/ V4 q* ~3 L& l P " v s+ B5 Z2 GThe Incredible Magdeburg Water Bridge in Germany , ^7 m7 J/ k ?8 a+ x. L ^5 @5.39.217.77:8898The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world. 2 q( m! ?( V5 G' v8 ] E. q ^The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo.

Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003. 5.39.217.77:8898% e; T2 ]% I' j! [: |1 I
