【摘要】 针对湖南宁道高速公路路基施工中出现的石灰岩质边坡快速恢复植被而展开仿生态复合技术研究。充分利用坡面凸凹垒砌鱼鳞燕窝槽,确定基材最佳组分配比(5∶2∶1)及草灌植物种子最佳配比(1∶4),筛选出垂吊类常绿藤本2种、攀爬类速生藤本5种、豆科类点播灌木3种。实践证明,仿生态复合技术能使大面积石灰岩质边坡迅速达到藤灌草复层结构(6∶3∶1),是一种成本低、效率高、效果好且环保的施工方法,技术较先进。更多还原

【Abstract】 This paper summed up the key construction technology with imitation ecological composite technology for a large area of limestone slope of the highway construction and development in Hunan Ningdao Highway roadbed construction.Making full use of slope surface uneven scales bird’s nest tank,optimum base material component ratio(5∶ 2∶ 1) and grass irrigation plant seeds ratio(1∶ 4),2 species of evergreen hanging liana,5 species of fast-growing climber vine,and 3 species of spot-sowed leguminous shrub were selected,and it was analyzed feasible through the integrated construction cost analysis and technical and economic comparison.It has been proved that the technology would soon bring about rattan stratified structure(6∶ 3∶ 1),with low costs,high efficiency,good effect and environmentally friendly.更多还原
