| 摘 要： | Dynamic contact theory is applied to simulate the sliding of surface fault.Finite element method is used to analyze the effect of surface fault to site ground motions.Calculated results indicate that amplification effect is obvious in the area near surface fault,especially on the site that is in the downside fault.The results show that the effect of surface fault should be considered when important structure is constructed in the site with surface fault.

| Abstract: | Dynamic contact theory is applied to simulate the sliding of surface fault. Finite element method is used to analyze the effect of surface fault to site ground motions. Calculated results indicate that amplification effect is obvious in the area near surface fault, especially on the site that is in the downside fault. The results show that the effect of surface fault should be considered when important structure is constructed in the site with surface fault. |
