Abstract

The strength characteristics of red clay are more complicated than ordinary clay, which directly affects the stability of infrastructure related to red clay. This paper proposes a novel relationship between the shear strength and void ratio of red clay using the existing fractal model to obtain its shear strength more effectively and practically in actual engineering. Through the cooperative analysis of fractal theory and physical properties analysis, the void ratio and shear strength of red clay can be quantitatively described using the fractal dimension. The accuracy of the relationship proposed based on the fractal model is verified by the shear strength of red clay at three stress levels obtained by direct shear tests in the laboratory. As well as proving that the proposed relationship has a good application effect on red clay, the shear test results also show that there is a positive correlation between the shear strength of the remoulded red clay samples and the particle size and the applied normal stress. The research methods and results provide a possible reference and theoretical basis for the application of fractal model to study the mechanical properties of red clay or other types of soil.
