Fractal Analysis on Shear Strength Properties of Bulky Rock Material in Waste Dump
The shear strength properties of bulky rock material were studied by the fractal geometry theory. The results show that: (1)The research indicates that the fractal dimension D can be a quantitative parameter of the particle composition of bulky rock material.and there was a clear linear correlation between the D and particle size distribution when bulky rock material was at good gradation.(2) Curve of stress-strain relationship had no obvious peak strength and it was strain-hardening. Gfailur and fractal dimension D have a obvious negative exponent relation while bulky rock material at the good gradation.(3) There was a negative exponent relation between φ and D at good gradation,but relationship of c and D was relatively disperse.
