- Abstract
To comprehensively consider the mechanical properties of miscellaneous fill, this study conducted triaxial experiments to investigate the strength characteristics of miscellaneous fill samples with different stone content, stone size, and dry density. The results reveal that, as the rock content increases, the cohesion gradually decreases and the friction angle gradually increases. As the rock size increases, the cohesion increases and the internal friction angle decreases. As the dry density of miscellaneous fill increases, the cohesion and internal friction angle gradually increase. Under a single factor, the cohesion and internal friction angle have a linear relationship with the rock content, fractal dimension of rock particles, and dry density of miscellaneous fill. Based on a single factor, a model for predicting the mechanical properties of miscellaneous fill under multiple factors is proposed, and it was confirmed that the proposed model has good accuracy. Thus, the strength parameters of miscellaneous fill under multiple factors were predicted.
