摘要
为解决单一工程护坡技术投资大、护坡效果较差的问题，对工程—生物复合护坡技术进行了试验研究。结果表明，工程—生物复合护坡技术具有投资少，坡面整齐、美观，护坡及绿化美化效果好等特点，且可节约沙石等建材０．１５ｍ３／ｍ２，减少护坡投资９．２元／ｍ２；护坡植被以苇状羊茅最佳，草皮移栽或种子直播均可，移栽后２０ｄ，平均株高１７．５ｃｍ，种子直播后２２ｄ，幼苗高度３～５ｃｍ。
This study was conducted during 1996～1997 on the Taiyuan Jiuguan highway in Shanxi province to test the effect of a combined engineering biological technique for stabilising the side slopes of the highway.In comparison to the case in which only engineering measures were taken,the new technique proved to be preferable,with a better viewing brought about by established turf grasses,enforced protection to the slopes and decreased cost.The best species of grass for side slope stabilisation appeared to be Festuca arundinacea,which can be established on slopes by turf transplantation or direct sowing.
