摘要

为了探索鱼线固定梅瓶文物在实际博物馆的地震响应以及抗震效果，首先选取了典型梅瓶文物，并在三层钢筋混凝土框架结构中开展了24种地震工况的振动台试验，然后建立了上述试验所用梅瓶文物的有限元模型，验证了有限元模型的准确性，最后采用增量动力分析法分析了该文物在两种常见直径鱼线保护措施下的运动响应。结果表明：鱼线固定梅瓶文物在地震作用下会产生滑移、摇摆、倾覆以及鱼线断裂等现象；不同楼层下的文物响应差别较大，尤其在大震作用下，高楼层的鱼线固定梅瓶文物易发生倾覆和鱼线断裂破坏，要重视高楼层文物的震前保护措施；在较强的地震作用下，仅依靠增大鱼线直径有时对控制文物的倾覆情况起不到关键性决定作用，需要进一步采取其它措施对文物进行保护。

Abstract

In order to explore the seismic response and seismic effect of the Plum vase cultural relics fixed by fishing line in the actual museum, the typical Plum vase cultural relics were first selected to carry out shaking table test of three-layer reinforced concrete frame structure under 24 kinds of seismic excitation. Then the finite element model of Plum vase cultural relics used in the above test was established, and the accuracy of the finite element model was verified. Finally, incremental dynamic analysis was used to analyze the motion response of the relic under two common fishing line diameter protection measures. The results show that the cultural relics fixed by fishing line may slip, sway, overturn and break under the action of earthquake. The response of cultural relics varies greatly under different floors. Especially under the action of large earthquakes, the cultural relics fixed by fishing line in the upper floors are prone to capsize and breakage of fishing line. Therefore, attention should be paid to the pre-earthquake protection measures of the cultural relics in the upper floors. Under the action of strong earthquake, only increasing the diameter of fishing line can not play a key role in controlling the overturning of cultural relics, so it is necessary to take other measures to protect cultural relics.
