| 摘 要： | 以某核电站的取排水工程为例，将典型核电地震波RG1.60谱人工波作为地震荷载，采用等价线性法对海洋土地基地下隧洞进行了平面有限元地震响应分析，通过计算总结了穿越不同的海洋土土质条件、不同埋深、管片接缝刚度、管片厚度及竖向地震对隧洞的衬砌受力与变形的影响，获得了此类盾构隧洞的动力响应特性规律，为隧洞抗震分析提供了参考依据。

| Abstract: | Taking water intake and drainage project of nuclear power plant for an example, equivalent linear method is applied to analyze two dimensional finite element seismic response of underground tunnel with ocean soil foundation by taking the typical nuclear power seismic wave RG1.60 as seismic load. The relationship between lining force of tunnel and deformation is analyzed under different soil conditions, different embedded depth, joints stiffness of duct piece, lining thickness and vertical earthquake. Dynamic response characteristics of shield tunnel is obtained, which provides reference for aseismic analysis of tunnel. |
