Abstract The use of geocell on slope to resist erosion is a green，economical and efficient protection method. Aiming at the problems of quantitative evaluation and engineering application of geocell reinforced slope，an analysis model of slope erosion under rainfall condition is established，and compared with existing geocell reinforced slope erosion test. Considering the interaction between the geocell and the slope soil，the study focuses on three working conditions：bare slope，laying only the geocell and planting grass in the geocell，and the erosion prevention mechanism of geocell reinforced slope is revealed. The effects of rainfall intensity，rainfall duration，slope gradient，slope length，geocell size and grass planting conditions on runoff and soil loss of geocell reinforced slope are comprehensively studied，and the parameter sensitivity analysis is carried out based on the anti-scouring effect of geocell reinforced slope. The research results show that the geocell can reduce the amount of soil loss by 20%–40%，and can effectively play a role in preventing the slope erosion. After combining with the function of plants，the amount of soil loss can be reduced by more than 90%. Among the parameters，rainfall conditions and geocell size have a significant impact on the anti-scouring effect of the slope，while the slope parameters have a relatively small impact. The study can provide reference for the optimization design of slope reinforced by geocell.

Key words： soil mechanics geocell rainfall slope anti-scouring parameter analysis
