尽管工程技术人员成年累月在工地调查,在计算机旁做分析,或在学术杂志上花几十年的功夫争论不休,但他们仍然弄不清楚一些大坝的失事原因。积年的分歧形成了固定的观念,乃至工程技术人员分成互相攻击,有时是互相敌对的派别。然而,哪怕专家们再有把握,他们也不得不承认,大部份 Although engineers and technologists are arguing endlessly throughout the months on site, doing computer analysis, or spending decades in academic journals, they are still confused about the causes of some of the dams. Disagreements over the years formed a fixed concept, and even engineering and technical personnel were divided into groups that attacked one another and were sometimes hostile to each other. However, even if experts are confident, they have to admit that most of them
