It is a particularly suitable method for shell dams.
這是一種對
殼體
壩特別適用的方法。
Analyses of the monitored seepage data of the sand case dam with clay core of jilihe reservoir show that the impervious effect of the clay core is good, that the blanket in the front of the dam has little impervious effect, and that seepage failure will probably take place because of the weak cutoff groove and the large seepage gradient
摘要對吉利河水庫粘土心?砂
殼壩的滲流觀測資料分析表明,該
壩粘土心?的防滲效果較好,但
壩前鋪蓋沒起到防滲作用,且截滲槽較薄弱,滲透比降較大,可能發生滲透破壞。
The gravelly soil is a better kind of damming material. it ' s usually used as impervious core and also as dam shell
礫質上是一種良好的築
壩材料,既能作防滲材料,又能填築
壩殼。
2 ) duncan e - u model is applied to the material of the dam. the feasibility of using duncan model is discussed. the duncan e ~ u model which considers the creep character of asphaltic concrete is adopted
壩殼材料選用鄧肯e -模型;討論瀝青混凝土心墻材料選用鄧肯模型的可行性,最終採用考慮瀝青混凝土蠕變特性的改進鄧肯模型。
