摘　　要：以罐 -液系统耦联振动规律为理论基础 ,对立式圆柱形储油罐的地震敏度进行了定量分析。储油罐地震敏度反应包括地震载荷引起的动水压力、基底剪力、倾覆力矩以及储液表面的晃动 ,地震敏度定量分析就是对这些参数做定量计算 ,从而对储油罐进行抗震设计。通过与《API 650》附录E和我国采用的《工业设备抗震鉴定标准》附录九的比较表明 ,新的地震敏度定量计算方法可对不同高径比的储油罐做地震敏度计算 ,物理概念清楚 ,计算过程简单明了 ,适用于工程中储油罐的地震敏度分析。On the basis of the regiilar pattem of coupled vibration of tanbliquid system, a quantitative analysis of the seismic sensitivity of the stand cylindrical ofl tank is niade The parameters of seismic sensitivity responses of an oil tank include dynaniic water pressure, base shear force, upsetting torque and shaking height of the liquid in the tank A quantitative calculation of these parameters is made, thereby the anti-seismic design of the oil tank can be done Companson betwesn API 650 Appendix E and Chinese Anti-seismic Design Standard Appendri 9 shows that, the calculation method of the seismic sensitivity presented in this article is simple and feasible
