《馆藏文物防震规范》关键技术——防震安全设计研究

Key technology of ‘Specifications for Seismic Protection of Museum Objects' ——research on seismic-proof safety design

《馆藏文物防震规范》WW/T 0069-2015,基于馆藏文物防震安全提出馆舍、展陈和文物全系统防震安全理念、设计方法和具体措施。本研究针对馆藏文物防震设计方法、适用范围、展柜及文物安全性判别等关键技术问题展开研究。首先,提出了"地震波+馆舍+展柜+文物"的全过程全系统防震设计理念;其次,针对浮放展柜及文物,进行地震作用下安全性分析研究;第三,与Getty博物馆研究成果对比,验证本研究理论的正确性与可靠性。分析得出:文物防震安全与文物高宽比、支撑接触面摩擦系数、安放处加速度峰值等因素有关;引入了抗滑动安全系数和抗倾覆安全系数进行设计,可充分保证文物安全性。

In the‘Specifications for Seismic Protection of Museum Objects＇（ WW / T 0069-2015）,a design method and specific measures for whole-system seismic protection safety,including the safety of buildings,showcases and collections is proposed based on the seismic protection safety of museum objects. In this article,several key technical issues related to the preservation of museum objects are investigated,including seismic protection methods,applicative scope,and an estimate of the safety of showcases and relics. First,the whole-system（ seismic waves ＋buildings ＋ showcases ＋ relics） seismic protection design idea is described. Secondly,a safety analysis study of free-standing showcases and relics under earthquake conditions is carried out. Thirdly,the accuracy and reliability of the theory is demonstrated by comparison with research result from the Getty Museum. It is concluded that seismic protection safety of the relics is connected with ratio of width to height,the contact surface friction coefficient and the vertical peak acceleration. The introduction of anti-slip and anti-overturning safety measures guarantees adequate safety of the relics.
