| 摘 要： | 根据地震作用、上部结构、桩基的特点，建立了建筑桩基地震反应分析的计算模型，考虑了桩-土-上部结构的动力相互作用。然后将饱和土体视为由固、液二相组成的两相介质，基于Biot动力固结方程，提出一种建筑桩基地震反应的有效应力动力分析方法，并给出了具体计算步骤。

Dynamic effective stress analysis for earthquake response of building pile found ations: Ⅰ--Computation method |

| Abstract: | According to the character of earthquake effect, superstructure and pile foundations, the research model of the earthquake response of building pile foundations is established. The model can consider the dynamic pile-soil-structure interaction. Based on Biot dynamic consolidation equation, which describes the two-phase porous media system dynamic interaction, the effective stress dynamic analysis with the model is recommended to predict the earthquake response of pile foundations. The calculation procedure is also reported in detail |
