摘　　要：我国西北黄土地区作为陆上丝绸之路的重要组成部分,应优先进行交通基础设施投资。由于黄土高原地形、地貌及地质极为特殊,在该地区修建高速公路时,往往需要克服高湿陷性黄土、高填深挖路基、植物防护难以成形等特殊困难,而路堑高边坡更是其中最大的难点。如何采用经济合理、优质高效的方法对高湿陷性地区的路堑高边坡进行开挖及防护已成为越来越热门的研究方向。As an important part of the terrestrial Silk Road,the loess area in northwest my country should give priority to investment in transportation infrastructure.Due to the extremely special topography,landform and geology of the Loess Plateau,when constructing expressways in this area,it is often necessary to overcome special difficulties such as highly collapsible loess,high filling and deep excavation of roadbeds,and difficulty in forming plant protection,and high cutting slopes are among them.the biggest difficulty.How to use economical,reasonable,high-quality and high-efficiency methods to excavate and protect high cutting slopes in high collapsible areas has become an increasingly popular research direction.
