Abstract:

Through compaction test of 2 kinds of fine-grained soil and 18 kinds of soil containing coarse granulae in the lab, the optimum compaction energy of the soil containing coarse granulae is studied when it is used as the embankment fill material. The test results show that the suitable test method of the maximum dry density for the soil containing coarse granulae is heavy compaction test; and the compaction times should be increased to 130 for each layer. The relationship between the maximum dry density and the granulae size group is analyzed through multiple linear regression; and the results show there is a good linear relationship between them.

Key words: the soil containing coarse granulae, maximum dry density, test method, affect factors, multiple linear regression
