超大粒径砂砾石坝料填筑标准的近似确定

Approximate determination of standard for embankment dam with super-size sandy gravel

结合工程实际顺粗粒料现有试验设备基础上，通过最大、最小密度试验，由实测粗闰料（ｄｍａｘ≤８０ｍｍ模型级配）的ρ＇ｄｍａｘ、ρ＇ｄｍｉｎ和超大粒径粗粒料（ｄｍａｘ≤４００ｍｍ原型级配）的ρｄｍｉｎ，来确定超大径粗粒料的ρｄｍａｘ，为鲺鲁瓦提面板坝工程提出了超大粒径砂砾石料填筑标准。

Considering the real condition and equipment for large size sandy gravel experiments,through maximum and minimum density tests, orienting from measured size gradation of sandygravel (dmax ≤80mm, model size gradation) ρdmax.ρdmin and the gradation of super size sandygravel (dmax≤400 mm) ρdmin to determine the ρdmax. for the super size gravel, providing the stan-dard of embankment for construction of Wuluwati Project, which is a rockfill dam with concreteslab facing.
