Triaxial test is widely used to determine the behaviour and strength parameters of soil. Several consolidateddrained triaxial compression tests were performed on two specimen sizes of sand and clay. This article investigate andcompares the influence of specimen size and scale effect on the soil shear strength. The tests results show that the shearstrength parameters are influenced by the clay specimen size. The results indicate that the effect of triaxial clay samplesize is more significant with higher confining pressures. The second type of tests carried out on sand samples shows thatsample size doesn‘t influence the results of the shear strength. Author’s show that clay analyses can be significantlyaffected by the choice of the specimen size used to determine shear strength parameters.
