| Abstract: | Based on lots of laboratory tests of Nan(ning)-You(yiguan) expansive soils,the relationship between shrink-swell and time of expansive soils is researched.The similarities and differences between shrink and swell are found.The quantitative correlation between deformation magnitude with different original water content and dry densities is explored. |

| Keywords: | expansive soil characteristic of shrink-swell curve for shrink-swell and time original water content and dry density |
