摘要储液结构(LSS)关乎战略资源的储备安全，在国防工程建设中备受关注，需要考虑武器爆炸时强烈冲击地震动对其动力响应的影响。利用爆炸冲击震动模拟平台开展了地面式矩形储液结构模型试验，研究了不同储液状态下储液结构在爆炸地震动下的动力响应，分析了地震动强度对结构振动加速度、结构应变以及动水压力的影响。此外，结合理论方法对储液结构壁板振型进行了探讨，对动水压力计算及相关设计规范的准确性与安全性进行了讨论。结果表明：储液增加使液固体系固有频率下降；结构动力响应与地震动峰值加速度相关性较高，随着地震动增强，不同储液状态下结构振动加速度、应变和动水压力均表现出强化效应；相较于无液状态，储液状态下结构动力响应随地震动强度变化敏感性提高，表现出更加显著的地震动强化效应；等强度地震动下，结构动力响应随储液增加而增强，说明储液结构处于高液位状态更加不利；沿壁板底部至顶部，结构振动加速度呈现放大效应，结构竖向变形符合剪切梁悬臂模型；动水压力的主要组成为脉冲压力，液面以下随水深增加呈现先增大后减小的趋势。动水压力标准值理论计算值偏于安全，基于理论方法修正了动水压力系数，给出了倾覆力矩系数。

Abstract：Liquid storage structures (LSS) are related to the security of strategic resources, which has attracted much attention in the construction of national defense engineering. It is necessary to consider the influence of ground motion caused by strong shock on the dynamic response of LSS when the weapon explodes. A series of ground-mounted rectangular LSS model tests have been carried out utilizing the explosion shock and vibration simulation platform. The dynamic response of the structure under different liquid storage conditions under explosive ground motions was studied, while the influence of ground motion intensity on structural vibration acceleration, structural strain and hydrodynamic pressure were analyzed. In addition, the vibration modes of the structural wall were discussed with theoretical methods. The accuracy and safety of hydrodynamic pressure calculation and related design specifications are discussed. The results show that the natural frequency of liquid-solid system decreases with the increase of liquid storage. The dynamic response of the structure is highly correlated with the peak acceleration of the ground motion. As the ground motion intensifies, the structural vibration acceleration, strain and hydrodynamic pressure under different liquid storage conditions all show strengthening effects. Compared with no liquid state, the dynamic response of the structure under liquid storage state is more sensitive to the variation of ground motion intensity, showing a more significant enhancement effect of ground motion. Under equal-strength ground motions, the dynamic response of the structure increases with the increase of the liquid storage, indicating that LSS with a higher liquid level is more unfavorable. Along the wall from the bottom to the top, the structural vibration acceleration presents an amplification effect, and the vertical deformation of the structure conforms to the shear beam cantilever model. The main component of hydrodynamic pressure is impulsive pressure. Below the liquid level, the hydrodynamic pressure increases first and then decreases with the increase of water depth. The theoretical calculation value of the hydrodynamic pressure standard value is on the safe side. Based on the theoretical method, the hydrodynamic pressure coefficient has been modified, and the overturning moment coefficient has been proposed.
