摘要
针对黄土地区场地条件的特点分析研究了场地覆盖层厚度和地形因素对地 震动放大效应的影响规律。通过对大量实际算例的归纳统计，给出了一种定量评价场 地覆盖层厚度及地形因素影响的经验方法。为黄土地震灾害预防及减轻技术研究提 供了参考依据。
The effects of overburden thickness and topography on earthquake ground motion are ana- lyzed in accordance with the particularity of loessial sites. An experiential method of evaluating ef- fects of overburden thickness and topography on ground motion is proposed based on a lot of sta- tistical data of seismic response of sites, which can serve as the basis for preventing and reducing the loessial disasters caused by earthquakes.
