Shear strength evaluation of preloaded stabilized dredged sediments using CPT
The undrained shear strength of preloaded stabilized dredged sediments increases with curing time. Evaluation of in-situ undrained shear strength using cone penetration test (CPT) data normally requires calibration of the CPT data with known undrained shear strength from vane shear test to obtain the cone factor, which is normally utilized in CPT empirical correlation to estimate the undrained shear strength. In this study, a new CPT empirical correlation for evaluation of in-situ undrained shear strength is presented. The proposed empirical correlation utilizes the effective vertical stress characteristic ratio to estimate the CPT induced stress, which was correlated to the in-situ undrained shear strength. The undrained shear strength computed using the proposed empirical correlation agrees reasonably well with the undrained shear strength estimated using the established empirical correlation at a large-scale field test. ; Godkänd; 2014; 20140304 (makusa)
