隔震技术在文物防震保护中的应用研究
|
摘要
地震不确定性给文物防震带来了挑战,基于博物馆、展柜和文物全系统的防震具有较强的现实意义.隔震技术的应用为传统文物防震保护提供了新的研究方向.本文所做的博物馆应用基础隔震数值分析表明隔震能够有效增强博物馆馆舍抗震性能.本文所做的陶瓷文物模拟振动试验表明隔震技术同样有效降低文物震动响应,但需注意馆舍与文物双重隔震时共振情况的发生.
Earthquake uncertainty brings challenges to the seismic protection of artifacts,and the seismic protection based on the whole system of museum,exhibition cabinets and artifacts has strong practical significance.The application of isolation technology provides the new research direction for the protection of the traditional artifacts.The numerical analysis on the application of base isolation in museum made by this paper shows that isolation can effectively enhance the seismic performance of the museum building.The simulated vibration test of ceramic artifacts made by this paper shows that the isolation technique is also effective in reducing the vibration response of the cultural relics,but it is necessary to pay attention to the occurrence of resonance in the double isolation of the museum building and artifacts.
