| 摘 要： | 对不同温度粗砂岩的干密度进行了研究,分析了粗砂岩的干密度经历了不同温度后的变化规律.结果表明:经历了高温后粗砂岩的干密度变化很小,没有明显规律性,在很多情况下可忽略不计.

| 关 键 词： | 粗砂岩 高温 干密度 抗拉强度 |

| Abstract: | Experimental study was performed on dry density of grit stone under different temperatures.The variable laws of dry density under different temperatures were analyzed.The results showed that the dry density of grit stone had small change after high temperatures which had no obvious law,and it could be neglected in many conditions. |

| Keywords: | Grit stone High temperature Dry density Tensile strength |
