中文摘要：

调查分析我国砂岩石窟岩体物理力学性质,采用标准砂、水泥、粉质黏土为原材料构建砂岩石窟室内模拟岩体;按照粉质黏土不同的掺入率设计了8组不同配合比的试样,对其密度、抗压强度进行了试验研究;采用有限单元法对抗压试验进行了数值模拟分析;该研究成果对构建砂岩石窟室内模拟岩体及相关的数值分析模型参数具有实用意义。

英文摘要：

Based on the investigation of physical and mechanical properties of sandstone grottoes,the standard sand,cement,silty clay are utilized as raw materials for forming laboratory simulating sandy rock mass.8 groups samples were prepared with different silty clay ratio,the density and compression strength of the samples are investigated.The compression test is simulated by finite element method and the practical model parameters are back-calculated.The results are helpful for making laboratory simulating sandy rock mass and numerical analysis.
