Research of Compressibility of Purple Soil in the Three Gorges Reservoir

Abstract:

Ecological restoration of soil slope has become an important content in the three gorges reservoir region. Based on the compression test of purple soil in the three gorges reservoir region, analyzed the index of compressibility, reflected the compactness of the different moisture content of purple soils, provided theoretical guidance for the ecological slope protection. Results of the trial indicated that the purple soils are the high-compressible-soil; the void ratio of purple soil reduces obviously with the increase of moisture content; with the increase of moisture content, the compression coefficient first increases and then decreases, and the compression index decreases gradually; but the compression modulus does not show a similar trend, it's minimum on the moisture content of 14%.
