| 中文摘要: |
| 本文提供了已衣定向爆破坝观测研究结果，主要是：(1)研究了坝体结构特性与渗透稳定机理；(2)进行两年直接挡水试验；(3)初步查明坝内渗流的水面分布、流态及水头损失；(4)给出了单宽坝体渗流量计算方法与经验表达式。 |
| 英文摘要: |
| The results of prototype observation of Jiyi rockfill dam by directional blasting are presented in this paper. 1.structural characteristics and the mechanism of stability against seepage flow of the damare discussed. 2.the highest water head loaded by the dam respectioely are 66.55m and 68.54m.2) 2 years water retaining test had been engaged without impervious element. 8.fallowing the conception of proposed. 3.The water surface distribution, flow pattern and head loss of seepage in the dam are investisuted. 4.An empirical formula and a method for calculating unit tam width seepage discharge of rockfill dam are given. |
