| 摘 要： | 储液罐的抗震性能虽然得到了较为深入的研究,但对其抗爆炸产生的地冲击作用的研究还十分罕见。本文通过建立流固耦合的数值分析模型,研究爆炸地冲击作用下地下立式储液罐的动力特性,包括储液晃动波高、罐壁的应力和应变、底板的提离和浮放储液罐的"象足"变形产生原因及破坏机理等。研究结果表明,储液罐在爆炸地冲击荷载和地震荷载作用下的动力响应有明显区别,地震荷载作用下的储液罐抗震验算方法不适用于爆炸地冲击荷载。

| Abstract: | The properties of earthquake-resistance of liquid-storage tanks have been investigated intensively.However,little attention is paid to the properties of blast-resistance of liquid-storage tanks,especially under the ground shock induced by explosions.In order to obtain a better understanding of dynamic response of the underground liquid-storage tanks subjected to the ground shock induced by explosions,numerical analysis of liquid and solid coupling is carried out in this paper.The analyses focus on the heigh... |
