未来的世界特大工程不少,这些工程的实现将给世界带来新的光辉。以下是设计中的几项特大工程。 真空高速地铁:这是美国21世纪骨干交通工程,只要21分钟便可从纽约到达洛杉矶。地铁时速为2百公里,计划引进日本的“磁悬浮”技术,整个隧道为真空装置,列车行驶中无空气阻力,可以获得极高的速度。这一未来的世界特大工程,并非天方夜谭,美国正在拟定工程计划。该计划如果投入实施,大致在2050年可以通车。 第二条巴拿马运河:目前的巴
The future of the world a lot of large projects, the realization of these projects will bring new glories to the world. The following is the design of several large projects. Vacuum high-speed subway: This is the United States 21st century backbone traffic engineering, just 21 minutes from New York to Los Angeles. Subway speed of 2 hundred kilometers, plans to introduce Japan’s “maglev” technology, the tunnel as a vacuum device, the train driving without air resistance, you can get very high speed. This future big project of the world is not a fantasy. The United States is preparing a construction plan. The plan, if put into operation, can be opened to traffic roughly in 2050. The second Panama Canal: the current Palestinian
