摘要: 利用可同步进行CT扫描的三轴仪,进行了不同围压下的三轴压缩试验。通过CT图像对分层击实重塑土压缩过程中微裂纹产生的过程及力学机制进行了探讨,得到了一些有益的结论。Abstract: The triaxial compression tests of compacted soil samples with different lateral pressures are conducted with a new set of modified triaxial compression apparatus with which the soil samples can be scanned by CT at the same time during compression process.The production mechanisms of micro crack in the soil samples during the damage process are analyzed and the failure modes are concluded from the point of view of fractural mechanics.
