Soft soil has obvious rheological character and it will induce subsidence distortion
landslide etc. serious geotechnical and geologic disasters
and make severe threatening to stability and security of projects. The initializing shear stress and viscosity of sullage soft soil are tested under static load; and the influencing characteristics are analyzed
of which the percentage of clay and water affect the rheological parameters. The mechanism of which the percentage of clay and water affect the rheological parameters are opened out by using the theoretical analysis and technology of structure micrograph. The research results have theoretical and practical significance for us to analyse changing disciplinarian of rheological parameters
reinforce soft soil foundation
raise bearing capacity and whole strength of soft soil.
