以一个6层砖结构和四种场地共同组建成四个结构一地基一体化计算模型，输入唐山地震基岩地表的余震记录，计算融土场地、有冻层场地和刚性地基三种情况下结构的地震反应，通过结构基底等效输入和结构地震反应内力的比较，作者认为，对绝大多数中软场地，用现行的刚性地基假设，作多层砖房震害预测是偏于安全的。
A six-storey brick structure and four kinds of venues are used to form four integrated structures-calculation models of ground-based structures. The aftershock records of the bedrock surface of the Tangshan earthquake are input to calculate the structure of the borrowed earth, the frozen ground and the rigid foundation Based on the comparison between the equivalent input of structural basement and the internal force of structural seismic response, the author believes that it is safe to use the existing rigid foundation assumption for the earthquake prediction of multi-storey brick houses in the vast majority of medium-soft terrains.
