本文主要对地基土——钢筋混凝土水下储油罐——可压缩流体相互作用体系在地震荷载作用下的地震响应进行了分析。考虑了流体可压缩性对齐水面和潜水圆柱体结构物的动水压力的影响。在数值计算中,分析了自由表面重力波及流体可压缩性及考虑流体的可压缩性与不可压缩性对相互作用体系动水压力和地震响应的影响。
This paper mainly analyzes the seismic response of the compressible fluid interaction system of subgrade soil-reinforced concrete storage tanks under seismic load. The effects of the fluid compressibility on the hydrodynamic pressure of the water surface and the diving cylinder structure were taken into account. In the numerical calculation, the effects of the free surface gravity wave fluid compressibility and the compressibility and incompressibility of the fluid on the hydrodynamic pressure and seismic response of the interacting system are analyzed.
