摘要

结合上海某地铁隧道工程 ,研究了隧道结构、周围土体及注浆材料的动剪应力、孔隙水压力及沉降量等的分布特征 ,评价了该隧道的抗震稳定性。采用了几种典型的地震波输入 ,对处于粘性土地层和砂性土地层中的隧道分别进行了动力响应分析。计算中 ,采用有效应力动力分析方法 ,并考虑了饱和软土的震陷对地下结构物抗震稳定的影响。
Taking a typical example of the tunnel which is located in soft soil stratum in Shanghai, the dynamic response of soil-structure located in soft clay formation under seismic loading is studied. In this calulation, the method of dynamic effective stress analysis developed by the authors is used and the developing and dissipation of water pressure in the process of earthquake is considered. Besides, several kinds of seismic acceleration curves are studied. The dynamic shear stress, pore water pressure and the settlement of the soft clay around the tunnel under 7 degree earthquake intensity are given, furthermore, the earthquake stability is ananlysed.
