Abstract:

Digital image processing technique developed by Dalian University of Technology is used to perform triaxial consolidation tests in order to study the collapse deformation of unsaturated remolded loess. The volumetric changes of samples can be accurately measured in consolidation process by the untouched measures technique. Relations between axial strain, radial strain, volume strain and time and relation between volume strain and stress are examined. Under the condition of fixed water content, the relationship between axial strain, radial strain, volume strain and time can be expressed in hyperbolic model, in which the parameter that stands for the final deformation depends on the uniform consolidation pressure.

Key words: remolded loess, digital image processing, consolidation deformation, triaxial test
