A Review of the Synergistic System of Micropile-Group-Soil-Vegetation for Slope Protection

Complex factors such as engineering geological conditions and rainfall usually determine the design of slope protection. According to the status of slope protection research, the significance of researching on the design methods of synergistic slope protection system of micropiles group-soil-vegetation is pointed out. Firstly, compared with other single means of slope protection in the aspects of construction, cost, environment, and safety, the new system has many obvious advantages. Subsequently, the mechanical mechanism of micropile-soil and the vegetation slope protection system were elaborated respectively from mechanical effects, hydrological effects and calculation models, and some problems are pointed out as well. Furthermore, the erosion and damage of soil slope under rainfall action are analyzed. Finally, the prospects of the application of the synergistic system in China are presented, and further research topics are suggested.
