  • Triaxial compression tests were performed on undisturbed and reconstituted Kitan clay to investigate elastic property of clay.Young Modulus of Kitan clay was measured during initial loading,after creep deformation,within small cyclic loading and global unloading-reloading.In order to measured strain smaller than 0.01% accurately,local displacement transducer(LDT) was used during the tests.The test results showed that:Young Modulus of undisturbed Kitan clay is much bigger than that of reconstituted one under the same stress level;Young Modulus of the same clay under high strain rate is bigger than that of small strain rate;Undisturbed Kitan clay showed perfect linear elastic property within small strain(smaller than 0.01%).
