| Abstract: | In this paper, taking Mogao Grottoes in Dunhuang, Gansu province, as the research object, the influence factors of dynamic damage for country rock of the grottoes under earthquake loading are explained. Using dynamic FEM, and based on the characteristics of ground motion caused by earthquake, the damage to the country rock and the subsidiary structures in earthquake is analyzed. The result could be used in the assessing earthquake security of historical relic grottoes and preventive measures. |
