| Abstract: | In order to evaluate and treat the silt subgrade diseases caused by rainfall of Beijing-Jiulong railway in the Yellow-River alluvial plain area,an indoor three-axis shear experiment on compacted silt soil of different densities and moisture content has been carried out.The rule that the deformation and strength of subgrade's silt change with the coeffi- cient of consolidation and the moisture content is generalized,which will provide ample experimental data for analyzing and evaluating the stability of silt soil railroad subgrade. |

| Keywords: | silt soil subgrade deformation strength dry density moisture content |
