| 摘 要： | 为保护天龙山石窟提供科学的依据，探讨了天龙山石窟工程地质特征问题。对天龙山石窟岩石进行了物理力学性质试验、化学成分和矿物成分分析，结果表明，天龙山石窟岩石为砾粗一中粒石英砂岩，石英含量高，化学成分以SiO2为主，胶结物以硅质最常见，胶结类型为孔隙式，属于坚硬岩石，但抗冻性差，抗风化能力中等。可见，天龙山石窟主要地质病害为岩体裂隙、窟顶渗水、岩体崩塌和石雕风化。

| Abstract: | Tianlong mountain Grottoes was cut on the precipice of the Formation of Permian Tenryu-ji.The mechanieal proper- ties of Tianlong mountain Grottoes sandstone were tested,the ehemicat composition and mineral composition of sandstone samples were analysised,and engineering geological problems were summaried. Tianlong mountain Grottoes is coarse gravel-medium-grained quartz sandstone, chemical composition of SiO2-based cement to the siliceous type of cement pore type, belong to the hard rock, but the frost resistance, weathering ability medium. Tianlong mountain Grottoes Geological diseases of rock fracture, making an seepage, rock collapse and stone weathering. In order to nrovide a scientific basis for protecting Tianlong mountain Grottoes. |
