The influences of partial saturation on cone penetration tests in silty gold tailings

Laboratory-controlled cone penetration test results of a silty gold tailings in variety saturated and unsaturated states, obtained using two calibration chambers, are presented then interpreted state parameter-based approach. The research was conducted as part the TAILLIQ project (tailliq.com), funded by Australian Research Council six mining companies, involving four universities.Cone resistances, which increase due to presence suction when unsaturated, can be normalised initial mean effective stress establish relationship with parameter. is applicable conditions, long hardening well influence on accounted for, penetrations occur under pseudo drained conditions. relationships enable parameters void ratios back-calculated from resistances.
