【 摘 要 】

Soil rock mixture is a non-continuous and inhomogeneous geological material. It is significant to quantitatively analyse the internal damage features and evolution laws of destruction of soil rock mixture. The traditional rock and soil mechanics test method and analysis theory don't perform very well. Therefore, a three-dimensional identification method of internal fracture and damage is proposed which based on image processing technology. In the uniaxial compression experiments, the features' changing of the internal microstructure is extracted and analysed. According to the changing, a three-dimensional reconstruction model of the rupture of soil rock mixture is constructed. Besides, the soil rock mixture with different stone content is analysed to receive the influence result of the internal damage. Experiments prove that this method can intuitively characterize the internal damage features and evolution laws of destruction in soil rock mixture.
