本文从岩相地质体特征和地质体地震反应特点等方面,探讨了唐山地震时北京郊区形成几个高烈度异常破坏区的原因。本文的结果和分析方法,为一个地区岩相地质体的地面运动分析和地震反应区划提供了一个有效的途径。
In this paper, the reasons for the formation of several high-intensity anomalous destruction areas in the suburbs of Beijing during the Tangshan earthquake are discussed from the characteristics of lithofacies and the characteristics of seismic responses of geological bodies. The results and analytical methods provided in this paper provide an effective way to analyze the surface movement and seismic response of the lithofacies in a region.
