摘　　要：京张高速铁路DK72+275-DK72+445段深路堑岩质边坡采用常规混凝土结构防护不能满足环保、经济等方面要求,因此总结目前广泛采用的各类绿色防护技术并调研其实施后的绿色生态防护效果,提出了采用GPI岩质边坡植被再造技术的边坡防护方案。该项技术克服了岩质路堑边坡难以绿化的困难,提高了岩质深路堑边坡与周边生态环境的适应性。采用GPI岩质边坡植被建造技术防护较传统钢筋混凝土框架梁结构平均节省43.4元/m^2,经济效益明显。The rock slope of deep cutting of section DK72+275—DK72+445 of Beijing-Zhangjiakou high speed railway is protected by conventional concrete structure,which cannot meet the requirements of environmental protection and economy.Therefore,summarizing the various green protection technologies widely used at present and investigating the green ecological protection effect after its implementation,the slope protection scheme adopting Geosynthetics-Plant-Intelligence ecological slope protection system was proposed.The technology overcomes the difficulty of greening the rock cutting slope and improves the adaptability of the rock deep cutting slope to the surrounding ecological environment.Compared with the traditional reinforced concrete frame beam structure,Geosynthetics-Plant-Intelligence ecological slope protection system can save an average of 43.4 yuan per square meter,with obvious economic benefits.
