通常所谓工程事故,大都指工程中的设计事故,或施工事故。实际上,从世界工程历史来看,面最大,性质最严重,处理最困难,影响最深远的工程事故,莫过于工程地质勘探事故。美国政府的一个专门委员会在对加利福尼亚州进行的一次工程调查中发现:在827座水坝中,竟有三分之二由于工程地质勘探不慎,存在着严重的地质问题,受到坍毁的威胁,有的已经坍毁。比如圣佛兰西斯大坝就是其中之一。其它如在1900年坍毁的美国柯罗拉多大坝,1928年坍毁的洛杉矶市水库大坝,1923年倾覆的意大利格里
The so-called engineering accidents usually refer to design accidents or accidents in construction. In fact, from the perspective of the history of the world’s engineering, the most serious and most serious nature of the world’s engineering history is that engineering accidents are the most difficult and most influential engineering accidents. A special US government commission conducted an engineering survey in California that found that out of 827 dams, as many as two-thirds of the dams were severely geological due to inadvertent engineering geological exploration and were threatened with smashing. Some have been destroyed. For example, the St. Francis Dam is one of them. Others such as the Colorado Corolla Dam destroyed in 1900, the Los Angeles City Reservoir Dam destroyed in 1928, and Italy’s Gerry capped in 1923.
