Abstract:

Based on the strain-controlled static tri-axial shear apparatus, the authors conducted a series of consolidation un-drained shear tests on manmade soil-rock mixture (S-RM) with different matrix bonding and block proportion by weight (WBP). The difference of the results with various matrix bonding as well as their causes of the difference were studied by a comparative analysis of the stress-strain relationship, pore pressure, effective stress path, and shear strength parameters. The test results show that the failure models of S-RM with different matrix bonding can be classified as shear band and bulge deformation damage. The different matrix bonding causes a big difference on stress-strain relationship and pore pressure. The matrix bonding strongly affects the mechanical behavior of dilation and the strain-softening of S-RM. The effective internal friction angle φ' of different bonding S-RM has a good liner correlation with the dimensionless parameter D50WBP/D60 under the similar conditions of the hardness,shape of rock, and the density of samples. The conclusions drawn from the test were significant and useful for obtaining the strength of a soil-rock mixture with different matrix bonding.

Key words: soil-rock mixture (S-RM), matrix bonding, consolidation un-drained shear tests, block proportion by weight (WBP)
