新台高速公路加筋草皮护坡技术研究

通过采用三维植被网结合喷播建坪防护边坡这一新技术的试验，对其施工技术、抗侵蚀作用以及该方式的经济成本进行研究。试验表明：该项新技术对细砂质量土、高液限土边坡、夹砂及碎岩土边坡进行防护，坡面土壤流失量是纯草皮防护区的20%以下，并且在台风带来的特大暴雨情况下，挂网试验区没有发生明显的浅表层滑移。与其他圬工护坡措施相比，加筋草皮护坡造价减少50%-70%，该项技术为因地制宜地进行坡面防护提供了一种新的办法和多样性选择。

Reinforced Turf Side Slope Protection Technology Study

This paper presents the experiment of new technology of side slope protection by 3-dimensional cover plant combined with jet seeding and discusses the construction technology,its erosion resistance function and the cost-benefit analysis.The experiment shows that the technology is effective for areas with fine sandy soil,high liquid limit side slope and sandy rock soil slope,with soil erosion 20% less than that in areas with simple turf protection and that there is no conspicuous surface layer sliding even under the condition of thunderstorm.In comparison with other side slope protection measures,the cost of the reinforced turf side slope is reduced by 50%～70%,which is new alternative method for side slope protection.
