A strong need, therefore, exists to develop a more practical method capable of simulating essential features such as liquefaction of the soil subjected to strong shaking. In this paper, a practical three-dimensional effective analysis coupled with a three-dimensional stress-strain model of sand is presented in which only soil properties obtained from a common field and laboratory test results. A key mechanism simulating liquefaction and cyclic mobility behavior is modeled based on the accumulated damage concept for pore pressure generation with a generalized hardening model for shear behavior. In addition, the composition rule that has been constructed for a one-dimensional shear stress-strain relation is extended to three-dimensional problems. To demonstrate the effectiveness of the proposed analysis, a large-scale field liquefaction test on soil-pile-structure models using blast-induced shaking is simulated. The computed results, including the acceleration and displacement responses of the structures, and the bending moment and axial stress in the piles as well as liquefaction and cyclic mobility behavior of the ground, are found to be in good agreement with the field test results. The good agreement suggests that the propose method, which requires soil parameters readily be obtained from common filed and laboratory tests, is convenient and yet effective in practice.
