Background
At present, along with the rapid development of mountain economy, various engineering construction projects are continuously promoted. Mountain expressway, hydraulic and hydroelectric engineering and municipal construction form a large number of exposed rock slopes. The side slopes can be classified into rock side slopes, soil side slopes and rock-soil mixed side slopes according to the properties of the components. The rock slope is usually referred to as a rock steep slope beside a mountain road, and has a great difference with the soil slope. Because of the physical and mechanical properties of the rock mass, the self-stability capability is stronger than that of a soil slope, and the slope is usually steeper. In addition, the rock slope has a large surface of rock, so that the water retention is poor and the soil is relatively barren, which makes it difficult to provide the substrate conditions necessary for vegetation growth.
