Stress-Strain Characteristics of Solidified Soil and Its Simulation

Tailings pond is a place for storing tailings or other industrial waste residues discharged from metal nonmetal mines after ore separation. The material will be into the stockpiling sorting and processing. hard to consolidate under natural conditions as result of high water content, resulting in certain safety risk pond. In this paper, tailing soil Huangshi City, Hubei Province studied triaxial consolidated drained shear tests materials different cement contents curing ages are carried out by using automatic apparatus. It made clear that stress-strain volume deformation solidified affected age confining pressure shearing. curves manifest themselves strain hardening type at low content they gradually change softening with increase content. has peak deviatoric stress during process shows phenomenon which disappears increases. test range, shrinkage process, its characteristics may simulated NHRI double yield surface elastoplastic constitutive model.
