| 摘 要： | 本文综述了场地条件对输入地震动的影响特征及国内外研究现状，着重讨论了场地土组合效应，覆盖厚度对地震动的影响。研究结果表明目前场地评价仅以场地的平均指标作为场地的评估标准不尽合理，应考虑场地土的组合效应，上覆地层的厚度及下部软夹层的影响。

| Abstract: | The research present situation at home and abroad relating to the influence of site condition on inputground motion has been introduced in this paper. It is emphatically discussed that the combination of site soil andthe thickness of covering strata have influence on ground vibration. The research results show that it is notreasonable to take cnly average index of site as estimating standard of site soil. |
