Dizhen xuebaoSmS震相是下行S波经莫霍面反射形成的地震震相，其大振幅特性可对距震中约100 km处的地震动产生显著影响。近年来，随着强震动观测网络的密集化建设，大量具有大振幅的清晰的SmS震相的高质量地震动记录被获取，推动了相关研究的持续深入。本文系统回顾了国内外关于SmS震相幅值特征及其发育机制的研究进展。早期研究表明：地壳结构条件与SmS震相发育密切相关，但部分研究在区域差异刻画和模型验证方面存在不足；后续相关研究通过引入更精细的地壳结构模型，并结合强震动记录分析 ...

Dizhen xuebao我国现行抗震规范中的加速度动力放大系数主要是依据国外强震动记录数据建立的，记录样本数量非常有限。随着国内近年来强震动观测资料的大量积累，有必要依托本土观测数据对该参数予以验证与修正。本文基于我国788条及国外10 276条强震动记录，对峰值加速度（PGA）归一化加速度反应谱进行统计，分别评估了地震震级、震源距离、场地剪切波速、覆盖层厚度等因素对PGA归一化加速度反应谱的影响，并分析了中国、美国、欧洲、日本之间的区域性差异。统计结果表明，PGA归一化加速度反应谱主要受地震震级和场地条件的影响 ...
