【摘要】 针对大型倒虹吸在复杂地质条件下的动响应问题,建立了考虑流固耦合作用的倒虹吸结构动力分析有限元模型。基于时程分析方法,对不同土层分布下结构的动应力及动位移进行分析。计算得出各地质条件下的动力响应分布规律,并表明通过换填土可以改善结构动力性能。更多还原

【Abstract】 For studying the dynamic response of the large inverted siphon under complex geological conditions,a FEM dynamic analysis model is established after considering the fluid-structure interaction.Based on the time-history method,the structural dynamic stresses and displacements in different soil distributions are analyzed and the distributions of the dynamic response under different geological conditions are obtained.The calculation shows that the structural performance can be improved by replacing soil.更多还原
