One of which is based on digital image processing (DIP). 2, 3 In practice, the traditional assumption of a homogeneous geomaterial is obviously insufficient for the exact analysis of SRM due to its multi-directionality and discontinuity.4, 5, 6Īt present, there are mainly two methods for constructing an SRM model. Because it widely exists in nature, SRM has been a rather interesting topic in the geotechnical engineering field such as landslides and mudslides. The soil-rock mixture (SRM) is a multiphase system composed of high-strength rock masses and low-strength soil, 1 which is a typical heterogeneous geomaterial. And the influence of block size distribution and rock content on the stability of soil-rock mixture slope has a coupling effect. The results show that the soil-rock mixture slope exhibits multiple sliding zone under the combined action of various plastic zone expansion. Furthermore, the stabilities of soil-rock mixture slopes with different block size distribution and rock content are investigated. Next, an improved intersection detection algorithm based on axis-aligned bounding box is developed to construct the digital model of the soil-rock mixture slope. Then, a corresponding rock block library is established. First, through digital image processing, a large number of rock block contours that are analogous with reality are obtained. Using this method, rock blocks of arbitrary shapes can be considered and the construction of soil-rock mixtures with different block size distribution and rock content can be realized. A new method for constructing a digital model of soil-rock mixture is proposed in this paper.
