摘要
应用动接触理论模拟断层的滑移问题,用有限元方法计算浅层断层对场地地震动的影响.计算结果表明,在地表断层出露的周围地区,断层下盘地表地震动放大效应较大,断层上盘地表地震动放大作用有明显的降低.这一结果说明,在有浅层断层的场地建设重大工程时需要考虑断层对地震动的影响.
Dynamic contact theory is applied to simulate the sliding of surface fault. Finite Element method is used to analyze the effect of surface fault on 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 projects are constructed on this kind site, where surface fault is exist.
