本文指出,我国水利水电工程现行设计规范存在的主要问题是,设计洪水标准偏高,按其规定所求得的设计洪水偏大,尤以重要水库大坝更为突出。其原因最主要的是借鉴国外经验结合我国具体情况研究不够,特别是受苏联四十年代设计洪水规范模式的影响太深。作者认为,我国水利水电工程现行规范亟需修订,降低标准,减小投资,以促进水利水电事业的发展。
This paper points out that the main problem existing in the current design codes of water conservancy and hydropower projects in our country is that the designed flood standard is too high and the design flood calculated according to its provisions is too large, especially for important reservoir dams. The main reason for this is that learning from foreign experience and studying the specific conditions in our country is not enough, especially because of the design flood norms model in the 1940s in the Soviet Union. The author believes that the current norms of China’s water conservancy and hydropower projects urgently need to be revised, lower standards and reduce investment in order to promote the development of water conservancy and hydropower.
