针对工程建设中出现的高陡边坡问题,开展了纤维加筋土对边坡绿化影响的研究。通过室外纤维加筋土模拟边坡绿化试验,对比了4种纤维含量,2种纤维长度和4级边坡坡率等因素影响下狗牙根的绿化效果。研究得出,纤维含量为0.2%的加筋土对植物初期生长有促进作用,长度为15 cm、含量为0.2%的纤维对植物的促进作用较其他配比的土样更为明显。对纤维加筋土边坡进行绿化不仅提高了边坡稳定性,还能修复因边坡开挖而破坏的生态环境。研究结果可供生产建设项目边坡绿化工作参考。

In view of the high and steep slope in engineering construction, research on the influences of fiber-reinforced soil on slope greening is carried out. Through the outdoor slope greening simulation experiments, the greening effect of Bermuda grass is compared under the influences of fiber content(0%, 0. 1%, 0. 2%, 0. 3%), fiber length(5cm, 15cm) and slope rate (1:0. 75, 1:1. 00, 1:1. 25, 1:1. 50). The results show that the soil with 0. 2% of fiber promotes the growth of Bermuda grass in the initial stage;the soil with 15 cm long, 0. 2% of fiber promotes the growth more obviously than the other soil samples. The greening of fiber-reinforced soil slope not only improves the slope stability, but also rehabilitates the eco-environmental damage due to slope excavation.
