岩石材料损伤变量与CT数间的关系分析

摘要: 本文在岩石损伤ＣＴ扫描实验结果的基础上，将岩石材料损伤ＣＴ数和岩石损伤变量联系起来．建立了用损伤ＣＴ数表达岩石材料损伤变量的公式，并和Ｂｅｌｉｏｎ、Ｌｅｍａｉｔｒｅ用材料密度表达的损伤变量公式进行计算分析比较．

Abstract: Based on the CT scanning experiment results of the damage of rock,the damage CT value is connected with the damage variable of rock material in the paper.The formula of damage variable expressed with its damage CT value are established,the numerical analysis are carried out,and comparied with Bellion and Lemaitre′s formula expressed with the density of rock material.
