摘　　要：地震小区划旨在估计研究区范围内地震作用的分布,为区内工程结构提供抗震设计依据。首先,对研究区地震活动性进行了评价;其次,收集并分析钻孔数据等进行了工程地质分区;再次,选取计算特征点计算获取了场地土层反应分析结果;最后,编制了地震动参数小区划图。小区划结果为西咸新区城市土地规划利用等提供了依据。Studing distribution of seismicity and providing the basis for seismic design of the study area is the pur- pose of seismic microzonation. Firstly, seismicity and seismic hazard of the study area were evaluated; secondly, data from borings was collected and analyzed, and engineering geological zoning was conducted; thirdly, site soil layer response analysis results were obtained by slecting feature points; at last microzoning map was drawn up. Mi- crozoning results provides a basis for urban land planning usage of Xixian New Area.
