摘　　要：生态边坡恢复初期,由于植被生长比较缓慢,强降雨对边坡的冲蚀破坏十分明显,造成了严重的水土流失。因此开展强降雨条件下边坡抗侵蚀性能试验研究,具有重大现实意义。结果表明:①有蜂巢格室防护的坡面其防冲蚀能力更强;②裸土坡的侵蚀量远大于有格室防护坡面的侵蚀量,且冲蚀量降低率最大为60%;③有格室防护的边坡比裸土坡体积含水率增长速度较慢,到达最大体积含水率时间也较长;④蜂巢格室防护使边坡的位移量明显降低,边坡平均位移量降低率下降明显,达到15.6%。In the early stage of ecological slope restoration,due to slow vegetation growth,heavy rainfall caused obvious erosion damage to the slope,resulting in serious soil and water loss.Therefore,it is of great practical significance to carry out the experimental research on slope erosion resistance under heavy rainfall conditions.The results show that:(1)the slope with honeycomb cell protection has better erosion resistance;(2)The erosion amount of bare soil slope is much greater than that of cell protected slope,and the decrease rate of erosion amount is up to 60%;(3)Compared with bare soil slope,the volume water content of the slope protected by cell increased slowly,and the time to reach the maximum volume water content was longer;(4)Honeycomb cell protection significantly reduces slope displacement,and the average slope displacement reduction rate decreases significantly,reaching 15.6%.
