PURPOSE: A dynamic viscoelastic-viscoplastic configuration model and a viscoelastic-viscoplastic interpreting method using the same are provided to estimate a dynamic conduct in a minute and small strain modulus area of a cohesive soil when a response of a multi-ground is interpreted. CONSTITUTION: Viscoplastic and viscoelastic conducting features of a cohesive soil are detected based on a viscoelastic-viscoplastic model. In order to grasp the viscoplastic and viscoelastic conducting features of the cohesive soil, a dynamic triaxial transformation test and a numerical simulation with the dynamic triaxial transformation test are performed. A method for cyclic undrained triaxial test on soils is used to estimate a conducting feature of the cohesive soil. The method for cyclic undrained triaxial test on soils breaks the cohesive soil by dynamic-loading a stress amplitude. In the dynamic triaxial test, a dynamic loading with respect to a loading frequency is performed using sine waves of 0.01 Hz and 0.05 Hz until an axial strain ratio alternating amplitude becomes 10%.
