| To investigate the engineering characteristics of crushed rockfill material, the large-scaled triaxial tests have been carried out, The rpckfill is made from the greywacke, and the 3 parallel gradations with different maximum particle size(dmu=38.1mm, 25.4mm and 19.1mm) were designed for the test. The dimension of the specimen is 300mm in diameter and 600mm in height, and the applied confining stress varied from 5t/$51.6^{circ}$ to 60t/$51.6^{circ}$. The test results show that the influence of the maximum particle size on the stress -strain r$51.6^{circ}; to; 40.5^{circ}$ when the confining stress increases from 5t/$51.6^{circ}$ to 60t/$51.6^{circ}$ The hyperbolic parameter values estimated from the test result for rockfill are much different from the recommended values by Duncan et. at(1980) for GW and GP material, especially in the $phi$ ad K-values. |
