| Abstract: | Summary Residual soils are known to be bonded. The mechanical behaviour of undisturbed residual soils depends, therefore, not just on initial porosity and stress history but mainly on these bonds. This paper compares the stress-strain behaviour obtained from sets of drained triaxial compression tests and direct shear tests, both from undisturbed samples of residual soil. It shows how the same undisturbed bonded structure behaves differently when tested using the two different procedures. |
