Abstract:

Effects of two specimen-preparing methods on tensile strength of remolded loess are studied. The first method adopts standard layered-bumping to make sample whose layer interfaces are vertical to tensile force (sample 1). The second method uses compaction apparatus to prepare big sample and the big sample is cut to prepare triaxial sample whose layer interface is parallel to tensile force (sample 2). Test results indicate that the sample 2 has higher tensile strength; and layer surfaces in sample 1 decrease its tensile strength.

Key words: remolded loess, specimen-preparing technique, tensile strength, layer interfaces
