The high slope is affected by various unstable factors, and becomes a multiple zone of geological disasters and engineering accidents such as landslide, collapse and the like.
Existing common slope protection technologies include engineering protection and plant protection. The simple engineering protection achieves the effect of stabilizing the side slope, but simultaneously, the underground water circulation path can be changed, the underground water is polluted, the gray appearance is reduced, the mood of pedestrians can be influenced, and particularly, the reflection of the protection surface facing strong light causes light pollution; while the simple plant protection can fix water and soil, reduce water and soil loss, reduce the risk of occurrence of debris flow, is attractive, and reduces the influence of human activities on the environment, the anti-slip and anti-collapse capability is limited, and the falling rocks cannot be completely prevented.
