【摘要】 针对矩形结构,采用拟静力方法详细探讨了土层刚度及土-结构相对刚度对结构地震反应的影响规律。结果表明,针对文中所研究的土体,地下结构设计时,要避开剪切波速为100m/s范围的土体;对于土层刚度的选择最好控制在200～400m/s之间。这对地下矩形结构的抗震分析、设计具有一定的参考价值。更多还原

【Abstract】 Pseudo-static method was used to analyze the influence of such factors as the stiffness of the soil and the relative stiffness on the seismic response of underground rectangular structure.In designing underground structures soil with shear wave velocity being about 100 m/s should be avoided.The best choice for soil stiffness should be between 200 m/s and 400 m/s.The results may serve as reference to seismic analysis and design of underground rectangular structure.更多还原
