摘要

在集中黏弹性人工边界基础上,利用谐响应分析和直接法探讨了基础埋置效应的核电站场地动阻抗与核电厂房结构地震响应的变化,并将计算结果与传统核电抗震设计规范的结果、经典解进行了比较。结果表明,基于输入条件不变的前提下,随基础埋置的加深,地基动阻抗实部与虚部随埋深均有增加,相应上部结构的地震动力响应降低,可供核电厂工程设计参考。
Based on the concentrated viscoelastic boundary theory,this paper studies the influence of foundation embedment on dynamic impedance and seismic response of the nuclear power station by using harmonic analysis and direct method.And the results are compared with the seismic design specifications of nuclear power and classical solutions.The results show that on the premise of the same input condition,as the foundation embedded deeper,both the real parts and imaginary parts of the foundation are increased with the embedment depth;the corresponding dynamic response of the upper structure is decreased.The results of this paper can provide some references for practical engineering.
