摘要
Abstract
The initial impounding of a core wall rockfill dam ,especially the impounding that takes place at a relatively high rate ,is the time when accidents would frequently happen ,which would probably cause certain adverse effect on stress deformation safety of the dam body ,for instance later deformation will in-crease and extend steadily and will even cause cracks due to core wall hydraulic fracturing .It is necessary to make a deep study on the initial impounding rate in order to ensure the dam safety .This paper studied the dam safety features and put forward the proposal of impounding rate in terms of the dam stress deform-ation and core wall hydraulic fracturing characteristic based on the high core wall rockfill dam of the Nuozhadu hydropower project .关键词
