原文系统地论述了混凝土坝设计技术的发展和现状,阐明了现有的一些重要的设计方法和准则在很大程度上都是过去经验的积累,坝工技术尚处于半经验半理论的状态。对此,讨论者深表赞同。但该文似对其症结分析不多,并对当前坝工技术的安全感偏重了一些,在此提出个人浅见,以供商讨。 对当前岩基上混凝土坝工作状况的调查和事故分析的资料表明:这类坝的事故约22％是由于过大
The original text systematically discusses the development and current status of design techniques for concrete dams. It is clarified that some of the important design methods and criteria are largely accumulated in the past experience. Dam technology is still under semi-empirical and semi-theoretical conditions. In this regard, the discussants strongly agree. However, the article seems to have limited analysis of the crux of the problem and places a lot of emphasis on the safety of current dam technology. I hereby put forward a personal opinion for discussion. The current investigation and accident analysis of concrete dams on rock foundations show that about 22% of the accidents of such dams are due to excessive
