| Abstract: | Through the normalization treatment of the compaction test data of sandy soil and compared with clayey soiL, this article performs a study and analysis of thc impacts of the sandy soil less than 0.075mm in grain size on the proctor curve. Summarizing and putting forward the compaction mechanism of sandy soil, it simultaneously makes an analysis of the impacts of grain size gradation and type of compaction on the compactness of the sandy soil and the solution thereto. |
