2004年12月,印度洋大地震引起的海啸造成超过29.2万人死亡,这可能是世界近200多年来死伤最惨重的海啸灾难。而在最早的防汛堤出现以前,依水而建的人类文明更是深受江河泛滥、海浪侵袭之苦。可想而知,堤坝对防洪挡浪是多么重要。堤通常是下宽上窄的墙形挡水建筑物。沿岸而修的堤常常与拦水的坝合称为堤坝。各式各样的堤为了与水抢地,人们建造了各式各样的堤,从最原始的土堤、木堤到石堤、砖堤,再到各种混合方式,最后发展出了现代的混凝土构造。
In December 2004, the tsunami caused by the Indian Ocean earthquake caused more than 292,000 deaths, which may be the world’s worst tsunami disaster in more than 200 years. Before the earliest flood control dike appeared, the human civilization built by water was even more afflicted by rivers and waves. One can imagine, dams dam flood control is how important. The dike is usually a wall-shaped retaining structure with a narrow width. The dikes along the coast are often referred to as dams with water-blocking dams. A variety of embankments In order to catch water and land, people built a variety of embankments, from the most primitive earth embankment, embankment to the embankment, brick embankment, and then to a variety of mixing methods, and finally developed a modern Concrete structure.
