Research on factors Influencing Characteristics Experimentation and Mechanism of Rheological Parameters of soft-soil

摘要

Soft-soil has obvious rheology character, it will induce subsidence distortion, landslide etc serious geotechnical engineering and geologic disasters, and make severe threaten 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 theory analysis and technology of structure micrograph. The research results have have theoretic and practical significance for us to analyse changing disciplinarian of rheological parameters, reinforce soft-soil foundation, raise bearing capacity and whole strengthen of soft-soil.
