本文提出了将土中箱形结构化为等效土层的等效层模型,并建议将土中箱形结构的动力反应分析按两步进行:第一步,对等效层模型进行波动分析,求出结构——土壤交界面处的相互作用力;第二步,将由第一步所得相互作用力作为荷载,将土中箱形结构如同地上结构一样,用一般结构动力学方法进行动力反应分析。文中给出了比较计算结果,说明所建议的模型和分析方法有很好的计算精度。
This paper proposes an equivalent layer model for the box-shaped structure in soil to a equivalent soil layer. It is suggested that the dynamic response analysis of the box-shaped structure in soil be performed in two steps: In the first step, the fluctuation model of the equivalent layer model is analyzed. Determine the interaction between the structure and the soil interface. In the second step, the interaction force obtained in the first step is used as the load. The box-like structure in the soil is the same as the above ground structure. analysis. The results of comparative calculations are given in this paper, which shows that the proposed model and analysis method have good calculation accuracy.
