Xiaojun Li, Lihua Jiang, Yichuan Tang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2010
The triaxial creep compression tests of compacted loess samples are conducted with a new set of modified triaxial compression apparatus. With the new apparatus, the loess 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 loess micro-crack during different creep compression processes are analyzed with CT images.
