英文摘要	The soil-structure interaction (SSI) is simulated by an artificial boundary, the pounding that occurs between the sliding base-isolated rectangular liquid-storage structure (LSS) and the surrounding moat wall is considered, the instantaneous pounding is simulated using the Hertz-damp model, and a simplified mechanical model with two particles and four degrees of freedom is established. Dynamic equation is obtained using Hamilton principle; effects of SSI, initial gap, and friction coefficient on the pounding responses under the action of near-field pulse-like Chi-Chi earthquake and far-field Imperial Valley-06 earthquake are studied. The results show that SSI will amplify liquid sloshing height but that structural acceleration and impact force will be reduced because of SSI. The responses caused by Chi-Chi earthquake are far greater than those of Imperial Valley-06 earthquake. Initial gap has a small effect on liquid sloshing height; structural acceleration and impact force first increase as the initial gap increases and then begin to decrease; in the design of moat wall of sliding isolation LSS, a certain gap exists that will more adversely affect the pounding responses of structure. Liquid sloshing height is less affected by coefficient of friction, but structural acceleration and impact force decrease as friction coefficient increases in general.
