摘要

应用流体固体动力耦合统一分析模型的有限元法,进行了储液池的抗震分析。分别探讨了储液池内液体的液面大幅波动、池壁刚度变化、池的深宽比等对地震响应的影响。研究结果表明:储液池壁刚度是比较敏感的物理量,弹性比刚性池壁与液体相互作用的非线性行为强,池壁所受流体的作用力大;液面波的影响也有同样规律,刚性池壁情况下考虑面波与否影响不太大,但弹性池壁却有较大影响;另外宽池比窄池的响应强。
The seismic analysis of liquid storage container is conducted by finite element method for transient dynamic fluid-solid coupling model. The influences of large amplitude surface wave,container wall stiffness change and container depth-width ratio on the responses of the liquid storage container subjected to earthquake are discussed respectivety. The study results indicate that the stiffness of liquid storage container is a sensitive physical quantity. The dynamic nonlinear interaction between the elastic wall of liquid storage container and the liquid is stronger than the rigid wall one and the dynamic water pressure acting on the elastic wall is larger than that on the rigid wall. The influence of liquid surface wave is bigger on the elastic wall than on the rigid wall. Moreover, the response of wide container is stronger than the narrow one.
