| 摘 要： | 将无粘性超径粗粒土的级配分为两部分，即粗粒部分和细粒部分，并将粗粒部分按相似原理缩尺到试验仪器允许的范围，对两部分分别测定其最大干密度，然后按两者的不同含量，从粗颗粒料及细颗粒料的结构性质出发，提出相应的公式，以推求其原型级配的最大干密度。

| Abstract: | In this paper, the gradation of oversized coarse grained soil is divided into two parts named coarse aggregate part and fine aggregate part respectively, then the gradation of coarse aggregate part is reduced scale to allowable range of experimental apparatus according to similitude law, so the maximum dry density of two parts can be tested respectively. According to the different particle content and compactness state of both parts, the formula to ascertain the maximum dry density of primary gradation coarse grained soil is presented |
