一、前言原油和液态天然气等大规模的能源贮藏设施,于国计民生和环境安全至为重要,因此必须具备较高的抗震性能。为使设计经济合理,必须进行详细的高精度抗震计算。为了建造油水交替式和内隔墙式等新型贮罐,必须弄清其动力特性,预测出其在地震时的反应。 I. Introduction Large-scale energy storage facilities such as crude oil and liquid natural gas are extremely important to the national economy, people’s livelihood, and the environment. Therefore, they must have high seismic performance. In order to make the design economically reasonable, detailed high-precision seismic calculations must be performed. In order to construct new storage tanks such as oil-water alternating and internal partition walls, it is necessary to clarify its dynamic characteristics and predict its response during an earthquake.
