世界水利学界公认,由于存在清除泥沙和防御洪水这两大技术难题,一般水利工程的寿命只有几十年。而我国闻名世界的都江堰水利工程,从古到今已经“活”了2250周年。远在两千多年前的蜀君守李冰,是怎样破解上述两大难题的呢?我国水利专家解开了这一奥秒。专家们通过对都江堰渠道的鱼嘴、飞砂堰和宝瓶口三大工程进行原型观测和模拟试验,利用弯道原理、地球自转原理和流体力学原理,反复推敲和论证,初步找到了都江
The world’s water conservancy has acknowledged that due to the two major technical problems of clearing sediment and preventing floods, the life expectancy of general water conservancy projects is only a few decades. The world-famous Dujiangyan Water Conservancy Project in our country has been “alive” for 2250 years since ancient times. As far as 20,000 years ago Shujun Li Bing, how to crack the two major problems? China’s water experts untied the Austrian seconds. Experts through the Dujiangyan channel fish mouth, flying sand weir and Bao-mouth prototype three prototype observations and simulation experiments, the use of curved corners, the principle of rotation of the Earth and the principle of fluid mechanics, repeated scrutiny and argument, initially found the Dujiang
