【摘要】 针对内罐泄漏条件下LNG储罐混凝土外壁,利用ADINA软件分别建立储罐空罐及满罐LNG储罐有限元模型。在El Eentro地震波作用下,考虑固液耦合作用,对储罐进行地震响应分析。结果表明:通过比较空罐与满罐情况下LNG储罐外壁的地震作用下的位移、加速度曲线,储罐的外壁受罐内LNG储液的影响较大,其位移和加速度在液固耦合的作用下,均较空罐变大。更多还原

【Abstract】 For concrete outer wall under internal leakage,finite element models of empty and full LNG storage tank are established with ADINA software.By inputting El Centro seismic wave,considering the liquid-solid coupling effect,seismic response of LNG tank is processed.The results show that with comparing displacement and acceleration changing curves of empty and full LNG tanks under earthquake,outer wall of tank is effected by liquid of LNG greater.With liquid-solid coupling,its displacement and acceleration all increased compared with empty tank.更多还原
