Abstract: Based on the comparing test among unconsolidated-undrained triaxial test, undrained triaxial test under equivalent consolidated condition and undrained triaxial test under K0 consolidated condition of the clay and sand in north anchor of RUNYANG big bridge,studying the influence of disturbed samples on natural strength parameter,the pretreatment method of resuming natural stress status of samples,analyzing the strength parameter of soil samples from different diameter samplers.
