摘要

摘要: 土壤-结构相互作用（SSI）会影响核电厂厂房的地震响应。本文充分考虑SSI效应的影响，对10 MW高温气冷堆（HTR-10）厂房在三向地震载荷下的响应进行了分析。建立了土壤-结构耦合有限元模型，通过构造人工边界实现对地震波在无限域内传播过程的模拟，并对模型的准确性进行了验证。利用该模型计算了HTR-10厂房的地震响应，并对不同楼层的反应谱计算结果进行了分析。对于水平向反应谱，各楼层的反应谱谱型类似，SSI影响规律基本一致。在竖直方向上，结构的响应特点与楼板自身的竖向频率特性有明显关系，不同楼板的响应差别较大。一般情况下，SSI效应对竖向响应有抑制作用，且随着楼层增加更为明显。当楼板与土壤的固有频率接近时，竖向响应与其他楼层相比会有显著放大。

Abstract: The seismic response of nuclear power plant is impacted by soilstructure interaction (SSI). In this paper, response of the 10 MW High Temperature Gas-cooled Reactor (HTR-10) under three-directional seismic excitation was analyzed considering SSI effect. The coupled finite element model of soil-structure was established, and the seismic wave propagation in infinite field was simulated by constructing the artificial boundary condition. Accuracy of the model was verified. The seismic response of HTR-10 building was calculated utilizing this model, and the response spectra of different floor levels were analyzed. In horizontal direction, the response spectrum shapes of each floor are similar, and the influences of SSI are basically the same. In vertical direction, the responses are significantly relevant to the vertical frequency characteristic of each floor, and responses of each floor are in large difference. In general, SSI inhibits the vertical response, and this effect becomes more remarkable as the floor increases. When the frequency of floor is close to that of the soil, responses of this floor have an obvious amplification compared with other floors.
