摘　　要：通过分析薄型窟顶的失稳原因并结合文物保护的加固原则,归纳出传统加固石窟窟顶技术的缺点,提出用钢梁吊顶结构加固窟顶的新方法,并具体介绍了该方法的加固措施和原理。结合新疆库车克孜尔尕哈石窟平共处第41窟现存情况,对加固前后的石窟窟顶进行稳定性分析和计算,结果表明,加固后的窟顶危岩体安全稳定,并且该加固方法最大程度地保存了历史信息,对文物干预最小。由此得出钢梁吊顶技术加固薄型窟顶石窟,是一种可靠有效的方法。This paper firstly analyzed the reasons for the failing of grottoes' celling,combined with the comparison of the previous methods of reinforcement for folium on the top of grottoes,a new method of strengthening the celling by using Steel ceiling was being proposed.And specific taked the No.41 grottoe of Kezier gaha in Xinjiang kucha as example,calculating and analyzing the stability of the top of the grottoe strengthened by the steel girder supported the top,the results show that the crag on the top of the grottoe is stable and safe after reinforcement ;this method mostly saves the historical information,and smallest intervents heritage.So we get the result that reinforcing the folium on the top of grottoes with the hidden-buried reinforced concrete structure is a reliable and effective method.
