Transcript of Seven wonders(1)
- 1. Introduction The American Society of Civil Engineers(ASCE) choose the greatest civilengineering achievements of the 20thcentury (1994) to be one of the SevenWonders of the Modern World. ASCE honored the following civilengineering marvels: Channel Tunnel (England & France) CN Tower (Toronto) Empire State Building (New York) Golden Gate Bridge (San Francisco) Itaipu Dam (Brazil/Paraguay) Netherlands North Sea ProtectionWorks (Netherlands) Panama Canal (Panama)
2. Empire State Building Finished being built in 1931 At 1,250 ft. the Empire StateBuilding is the best-knownskyscraper in the world, andwas by far the tallest buildingin the world for more than 40years. The buildings mostastonishing feat however, wasthe speed in which it rose intothe New York City skyline. Construction was completedin only one year and 45 days,without requiring overtime. 3. Itaipu Dam Spans the Parana River atthe Brazil/Paraguay border. The Itaipu Dam is theworlds largest hydroelectricpower plant. Completed in 1991, it took16 years to build this seriesof dams whose length totals7,744 m. It used 15 times moreconcrete than the ChannelTunnel. 4. Channel Tunnel Known as the Chunnel, theChannel Tunnel linksFrance and England. It is 31 mi (9 m) long, and23 of those miles are 150ft (45.7 m) beneath theseabed of the EnglishChannel. Through two of the tubesrush the broadest trainsever built -- double deckerbehemoths 14 ft. across --traveling close to 100mph. 5. Panama Canal The Panama Canal is one of civilengineerings greatest triumphs. It took 34 years to create this 50-mile-long canal across theIsthmus of Panama. The amount of digging requiredand the size of its locks helpedmake it the most expensiveproject in American history atthat time. It was also the most deadlyproject in American history:About 80,000 people died (mostfrom disease) duringconstruction of the PanamaCanal. 6. CN Tower From 1976 to 2007, the CNTower was the worlds tallestfreestanding structure. It looms about one-third of amile high (1,815 ft) aboveToronto, Canada. It was built at an amazing rate of18 ft. per day. Designed with the aid of a windtunnel, the CN Tower canwithstand 260-mph gusts. The SkyPod, a seven-storystructure 1,100 ft. high, wasbuilt around the base of thetower. 7. Netherlands North Sea ProtectionWorks This vast and complex systemof dams, floodgates, stormsurge barriers and otherengineered works literallyallows the Netherlands toexist. The biggest part of theNetherlands North SeaProtection Works was a two-mile-long moveable surgebarrier across an estuaryfinished in 1986. It is made of 65 concrete pierseach weighing 18,000 tons. 8. Golden Gate Bridge More than 60 years after itscompletion, the Golden GateBridge remains the worldstallest suspension bridge. It connects San Francisco andMarin County. It took about four years tocomplete the beautiful 1.2-mile-long (1.9 km) bridge. It is held by 80,000 mi (128,747km) worth of steel wire. Hanging from two 746-ft-hightowers, its cables -- each a yardthick --are the biggest ever tosupport a bridge. 9.
