| 摘 要： | 在有效应力动力分析方法的基础上,采用等效线性化方法的动力计算模型,研究了在7度地震下隧道-土体体系的地震反应.计算中采用唐山地震波作为水平输入的地震波,得到隧道周围土层的反应加速度、动孔压比、动剪应力比等地震反应,并估算了地基土的震陷值,为工程的抗震措施提供必要的参考依据.

| Abstract: | Based on the method of dynamic effective stress analysis,the seismic response of tunnel-soil system is studied by dynamic model with equivalent linearity.Tangshan seismic waves are put into the analytic model in horizontal direction,and the transient response in time history is analyzed.The horizontal acceleration response,pore water pressure ratio,dynamic shear stress ratio,as well as soil subsidence are calculated to supply necessary reference to the construction. |
