摘要
以黄河干流上某水利枢纽基本资料为依托,在分析坝基基本地质条件、坝基土体工程性质的基础上,从坝基土体组成及工程特性、水库运行期的淤积效应两方面,对深厚覆盖层坝基防渗进行了探讨。此外,坝区风积沙广泛分布,依据现行水利水电行业规程,结合场区风积沙的特性,对风积沙作为筑坝材料的可行性进行了初步分析。
By reference of the basic data of a water control project on the main course of the Yellow River and on the basis of basic geologic condition and soil property of the dam foundation,antiseepage of deep and thick overburden is discussed from the points of soil composition and project feature of the dam foundation and reservoir sedimentation in operation period.In addition,due to the wide spread of aeolian sand in the dam area,the feasibility of taking aeolian sand as materials for dam construction is preliminarily analyzed by reference of prevailing hydraulic and hydropower standards and in combination of the feature of aeolian sand.
