摘要
唐代惠明寺塔为河南省重点文物,其结构的安全性能为文物专家所关注。结合惠明寺塔的砖石结构特点和历史根源,讨论了中国砖石古塔的抗震机理,探讨了砖石古塔的动力特性。为对塔的抗震安全性能进行合理的评价,依据现代地震工程理论和有限元分析方法,建立了塔的三维计算模型,通过对模型输入1940 El Centro地震波,得到了塔体关键部位的加速度、速度和位移,对塔的抗震能力进行了分析,分析结果为安阳惠明寺塔的抗震加固提供了理论依据。
Huiming Temple Tower in Tang Dynasty is an important ancient building and its security is cared by experts. According to the design feature of Huiming Temple tower, aseismic mechanism and dynamical characteristic of ancient masonry tower are discussed. Calculating model of Huiming Temple tower is built by modem earthquake theory and FEM. Based on the tower model, the acceleration, velocity, displacement of key part, the shear and moment at the base are obtained to analyze earthquake-resistance capacity of the tower. Research results will provide theory helping earthquake-resistance reinforcement of the tower.
