- Abstract
The compaction rate of gravel soil is usually characterized by the “relative density”. In order to calculate the relative density of gravel soil, the relative density property index of soil should be determined firstly, such as the maximum dry density and the minimum dry density. Because of the size and energy limitation of the laboratory test equipment, The maximum dry density of the gravel soils determined in laboratory tests is often much lower than the actual. For the Yulongkashi high earth-rock fill dam in China, the field large-scale relative density tests of original gravel soil was carried out used actual rolling equipment and large relative density bucket, the compaction characteristics of soil was studied, and the relative density characteristics index of soils with different gradation (coarse grain content) were determined. The test results showed that, compared with the general laboratory test results, the maximum dry density of gravel soil determined by field test was much larger; the minimum dry density as well as maximum dry density of gravel soil had the tendency of increasing and then decreasing with the increase of coarse grain content, and there was an optimum coarse grain content for the density of soil.
