1975年,在河南省驻马店等地区1万多平方公里的土地上,共计60多个水库相继发生垮坝溃决,近60亿立方米的洪水肆意横流。1050万人受灾,超过2.6万人死难,倒塌房屋524万间,冲走耕畜30万头。纵贯中国南北的京广线被冲毁102公里,中断行车16天,影响运输46天,直接经济损失近百亿元,成为世界上最大最惨烈的水库垮坝惨剧。30年后,反观这次垮坝事故,从中折射的问题更值得深思。 In 1975, over 60,000 cubic meters of land were destroyed in more than 60 reservoirs in a total area of ​​more than 10,000 square kilometers in Zhumadian, Henan Province. Nearly 6 billion cubic meters of floods were indiscriminately crossed. 10.5 million people were affected, more than 26,000 people died, 5.24 million houses collapsed, and 300,000 livestock were washed away. The Beijing-Guangzhou line running north and south of China was washed down 102 kilometers and the traffic was interrupted for 16 days, affecting 46 days of transportation. The direct economic loss was nearly 10 billion yuan, making it the largest and most tragic reservoir collapse in the world. After 30 years, on the other hand, the problem of this collapse accident and refraction from it is even more worth pondering.
