摘　　要：本文根据西安市阎良区及周围地区的地震地质环境,在地震危险性分析的基础上,采用等效线性一维波动方法进行土层地震反应分析。计算得出50年超越概率63%、10%和2%的地面水平向峰值加速度,该结果为该地区抗震设计提供了依据,具有应用价值。Considering the seismic environment of Yanliang District, Xi＇an and its surrounding area, the soil seismic response is analyzed by using equivalent linear one-dimensional wave equation on the basis of seismic risk analysis. Calculation results include 50 years probability of exceedance 63%, 10% and 2% of the horizontal peak accelerations. The results can be used in design of earthquake engineering in this area.

关 键 词：地震危险性分析 地震反应分析 峰值加速度
