喷混植生技术在边坡防护中的试验研究

Experimental Study on the Soil-seed Spraying and Planting Technology Applied in the Side Slope Protection

岩石边坡生态恢复与治理技术是目前高速公路建设中的一个热点问题,由于岩石边坡上缺少植物生长所需要的土壤条件、养分及水分条件,不能直接通过植树种草进行生态恢复,因此岩石边坡的生态恢复与治理问题急待解决。本文重点阐述了平乐至钟山高速公路K139+450～150+575路段的路堑岩石边坡采用喷混植生技术所进行的生态恢复与治理试验情况,并对试验结果进行分析,对试验中产生的问题进行了探讨,提出了完善此项技术需要进一步研究的内容及方向。

Ecologic restoration and treating technology for rock slope is now a hot spot in expressway construction.As the rock side slope is lack of soil,nutrient and water that are necessary for plant growth,the ecologic restoration can not be done directly through planting tree and grass.Thus the ecologic restoration and treatment on the rock slope is an urgent problem to be resolved.The Paper mainly presents the experiment of ecologic restoration and treatment on the rock slope at K139+450~K150+575 of Pingle to Zhongshan Expressway,and has an analysis on the experimental result.Through a study on the problems occurring in the experiment,the Paper proposes the improvement items and direction of this technology that need further study.
