本文综述了现有考虑贮液罐提离机理的两种计算理论。震害调查和实验证实,地面运动过程中部分罐底提离和罐壁失稳紧密相关。但现有预测失稳应力的理论模型准确度很差,急待改进。建议在这一领域开展研究,争取尽快将成果列入我国贮液罐抗震设计规程。 This paper summarizes two existing calculation theories that consider the lifting mechanism of the storage tank. Earthquake damage investigations and experiments confirmed that the lift of part of the bottom of the tank during the ground movement is closely related to the instability of the tank wall. However, the accuracy of the theoretical model for predicting the instability stress is poor and it is urgent to improve. It is recommended to conduct research in this area and strive to include the results as soon as possible in the anti-seismic design regulations for China’s liquid tanks.
