你見過一條河流過另一條河嗎？

 Have you ever seen a river over a river? AMAZING.....

 

你見過一條河流過另一條河嗎？ AMAZING.....

Even after you see it, it is still hard to believe!
Water Bridge in Germany . What a feat!

Six years, 500 million Euros, 918 meters long . . . now this is engineering!

This is a channel-bridge over the River Elbe and joins the former East and West Germany ,
As part of the unification project. It is located in the city of Magdeburg , near Berlin .
The photo was taken on the day of inauguration . . .

To those who appreciate engineering projects, here ' s a puzzle for your armchair engineers
. . . and physicists.

Question:

Did that bridge have to be designed to withstand the additional weight of ship and barge traffic,
Or just the weight of the water?

Answer:

It only needs to be designed to withstand the weight of the water!

Why?

A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded.

即使你看到它，它仍然是很難相信！
水橋在德國。什麼的壯舉！
六年來​​，500萬歐元， 918米長。 。 。現在這是工程！

這是一個通道橋在易北河和加入前東德和西德，
由於部分項目的統一。它位於城市馬格德堡附近的柏林。

對於那些誰欣賞工程項目，這裡有一個難題的工程師為您的扶手椅
。 。 。和物理學家。

問題：難道是橋樑設計必須承受額外的重量船舶和駁船運輸，
或者僅僅是重量的水？

答：它只需要設計承受重量的水！

為什麼呢？
船舶總金額取代水的重量一樣的船，無論怎樣嚴重的船舶可裝載。

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. 易北河 - 哈維爾運河和Mittelland此前會見了馬格德堡附近，但對立雙方的易北河。兩者之間的船舶移動不得不作出一個 12公里長的彎路，降從 Mittelland運河船隻通過 Rothensee電梯到易北河，然後順流河上，在進入易北河 - 哈維爾運河通過 Niegripp鎖。低水位在易北河往往使運河駁船滿載作出這條通道，需要耗時卸貨物 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. 建水的聯繫始於早在20世紀 30年代，但由於​​第二次世界大戰和隨後的分裂德國的工作依然暫停，直到1997年。該渡槽終於完成，向公眾開放於 2003年。
