佛教石窟艺术是中国悠久而灿烂的古代文化的重要组成部分 ,也是极其珍贵的文化旅游资源。地震区的石窟文物保护工作必须科学地估计它可能受到的地震威胁。本文以莫高窟为例 ,结合本区的地震地质环境、历史地震特征以及场地条件 ,探讨了石窟地震安全性评价的工作原理和分析方法。文中所给出的不同概率水准的地震动参数可作为莫高窟动力分析和抗震加固设计的理论依据。
The art of Buddhist grottoes is an important part of China’s long and splendid ancient culture and is also an extremely valuable cultural tourism resource. Earthquake caves cultural relics protection work must be scientifically estimated that it may be the threat of earthquakes. Taking the Mogao Grottoes as an example, this paper discusses the working principle and analytical method of seismogenic seismic safety assessment in combination with the seismo-geological environment, historical seismological features and site conditions in this area. The ground motion parameters with different probabilities given in this paper can be used as the theoretical basis for the dynamic analysis and seismic strengthening design of Mogao Grottoes.
