摘要
英布鲁水电站拦河坝为土质防渗体分区坝,用太沙基设计准则对上、下游坝坡渗流出逸处进行反滤设计。由于几种筑坝材料的抗渗性能较差,对设计的反滤级配进行试验验证,结果表明,本工程的反滤层按太沙基设计准则进行设计是合理的,能满足防止大坝渗透破坏的需要。
The dam for Imboulou Hydropower Station in Congo is a soil impervious zoned earth dam;for which a filtration design is made for the escaping points of seepage flow on the upstream and downstream slopes in accordance with Terzaghi design criteria.As the poor impervious performances of several dam filling materials therein,the relevant experimental verification is made on the designed filtering gradation and it is demonstrated that the design of the filter layer for this project is reasonable and then can satisfy the demand to prevent the seepage failure of the dam.
