| 摘 要： | 对某枢纽工程坝体填筑料进行了多组相对密度试验。采用混合法对原级配料进行处理,测定系列模型级配料的最大、最小干密度。采用延伸法推求实际级配的最大、最小干密度过程中,充分考虑级配料干密度上、下边界值的影响,并按设计压实度标准换算出现场控制干密度。

| Abstract: | Multi group relative density tests have been taken for the filling materials in dam body of a pivotal project.The primary gradating material was dealed with hybrid method.Maximum and minimum dry densities of the gradating material in series model have been determined.The influence of gradating material top and bottom boundary value has been considered during the evaluation of practical gradation maximum and minimum dry density with extension method.The field control dry density was conversed according to design compactness standard. |
