论阿哈水库红粘土隔水斜墙的“阿哈效应”

Re - examination of Impermeablity of the inclined Dam WallBuilt in the Aha Reservoir of Guiyang City, Guizhou

贵阳市阿哈水库始建于1958年，主要由贵阳市民参加义务劳动修建，缺乏施工机械，工期短，红粘土隔水斜墙的填筑质量较差，但已正常运行36年，并经历了1991、1996年特大洪水，通过首次质量检验认为：阿哈水库红粘土斜墙是隔水的、稳定的，仍具备继续正常运行的基本条件。

The dam of the Aha reservoir built in 1958 was thought to be poor in fillingquality thanks to its construction ahead of schedule in the case of lacking necessary equipment andfacility and almost with the help of volunteers. After its serving for 36 years, especially suffering fromtwo abnormal floods of 1991 and 1996 in historic time, the dam was re - examined by moderntechniques. This paper presents a conclusion on its engineering evaluation.
