| 摘 要： | 利用大型通用ADINA有限元分析软件进行动力分析,研究石窟在地震作用下的稳定性问题.通过瞬态分析,指出了石窟结构在地震荷载作用下的薄弱部位,并且给出在易被破坏位置上的节点的位移时程和易被破坏位置上的单元的主拉、主压应力时程曲线.计算结果表明地震作用下薄弱部位多数发生在石窟的脚点附近,在有裂隙的部位打入锚杆对石窟整体结构的安全性是有益处的.

| Abstract: | The steady of Grottoes attacked by earthquake is analyzed with the engineering soft named ADINA,in order to show where the weak parts of Grottoes are and Time-history curves of the horizontal displacement of the easily damaged nodes and Time-history curves of first and third principal stress of the easily damaged elements. The results show that the weak parts of Grottoes often are nearby at the corners of Grottoes and that to employ the anchoring steel-bars in the gaps does good to the safety of the whole structure of Grottoes. |
