CT Discrimination of Fabric Change of Unsaturated Compacted Loess during Compression Process

摘要

The triaxial compression tests of compacted loess samples with different lateral pressures are conducted with a new set of modified triaxial compression apparatus which. With the new apparatus, the soil sample can be scanned with CT machine at the same time during compression process. The different damage process of compacted loess sample is directly observed for the first time with CT images and CT numbers. The initiation mechanisms of soil micro crack during different processes are analyzed with CT images.
