深浅液位下储液罐振动台试验研究
Shaking table test study on liquid storage tanks under shallow and deep liquid levels
摘要
Abstract
As typical thin-walled structures,liquid storage tanks are prone to structural instability and liquid leakage under seismic excitation,which may trigger secondary disasters such as fires and explosions,resulting in severe economic loss and environmental pollution.Liquid level plays a critical role in the sloshing characteristics of storage tanks.To reveal the effect of liquid level variation on storage tanks,the dynamic response characteristics of storage tanks with varying liquid levels were investigated.To mitigate severe liquid sloshing,a measure involving the installation of baffles-wire mesh inside the storage tank was proposed.Shaking table tests were conducted to analyze the sloshing height,structural strain,and acceleration responses,and the mitigation performance of the storage tanks was comparatively evaluated.The experimental results indicate that the baffle-wire mesh can effectively suppress liquid sloshing and reduce the structural response of the tank,with the mitigation performance improving as the wire mesh arrangement density increases.Under shallow liquid level conditions at a peak ground acceleration of 0.2g,the reduction in dynamic water pressure for the storage tank with densified wire mesh reaches 55％-65％,compared with 35％-45％for the non-densified condition.A comparison of different liquid-level conditions reveals that the average reduction rates of various response parameters are generally greater at the shallow liquid level than deep liquid level,indicating that the proposed mitigation measure is more effective under low liquid-level conditions.In addition,the mitigation measures for the storage tank are more effective under lower peak ground acceleration levels.关键词
