This is lower than other results of 2-3 orders of magnitude; but it is consistent with the result of no severe grain crushing.
这比其他2 ~ 3个量级渗透性降低的结果小,但与试验中岩石颗粒破碎不严重相符合。
The grain crushing of rockfill materials with high stress level has significant influence on its strength and deformation mechanisms.
高应力水平时堆石料的颗粒破碎对其强度和变形机制有重要影响。
For high rockfill DAMS, the grain crushing in high stress field may raise the deformation rate of dam body and should be considered in numerical calculation.
对于高堆石坝而言,在高应力场作用下堆石颗粒将明显破碎,从而导致坝体变形率增加,因此,在高坝数值计算中必须考虑颗粒破碎的影响。
