摘要
地震灾害对文化遗产的影响极大,为预见地震灾害对石窟寺的影响,从致灾因子、孕灾环境、承灾体、防灾减灾能力等4方面构建了石窟寺地震灾害风险评估模型,确定了地震动峰值加速度、场地类别等23个因子组成评估指标体系,并以云冈石窟为例进行评估。结果表明:云冈石窟中有44%的洞窟地震风险较高,主要集中于西部窟区,整体上呈现西高东低的趋势,与实际结果较为符合,说明石窟寺地震灾害风险评估模型可以对石窟寺地震灾害风险进行定量风险评估,为石寺预防性保护及加强防震减灾管理提供科学依据。
Earthquake disasters have a great impact on cultural heritage.In order to predict the impact of earthquake disasters on grotto temples,an earthquake disaster risk assessment model for grotto temples was established from four aspects:disaster-causing factors,disaster-pregnant environment,disaster-bearing bodies,and disaster prevention and mitigation capabilities.The evaluation index system,which consists of 23 factors such as peak ground motion acceleration and site category,was determined,and the Yungang Grottoes was taken as an example.The results showed that 44%of the caves in the Yungang Grottoes had higher earthquake risk,mainly concentrated in the western area,showing a trend of high in the west and low in the east as a whole,which was in good agreement with the actual results.It showed that the model could quantitatively evaluate the earthquake disaster risk of grotto temples,and provide scientific basis for the preventive conservation and earthquake prevention and disaster reduction managements of grotto temples.
