摘　　要：黄土高原特殊的地质条件与土力学特征导致黄土地区滑坡问题严重。黄土地区交通线路,尤其是高铁路基边坡生态防护(修复)已成为水土保持与工程地质等领域的重要研究问题。以西延高铁黄土路基为例,从黄土地区滑坡的致灾机理、黄土路基边坡的防护措施及黄土地区生态修复技术3个方面,梳理黄土路基边坡生态防护(修复)研究取得进展、适用范围以及未来发展趋势;从工程措施、生物措施和排水措施3个方面,论述西延高铁采用的具体边坡防护技术,并对黄土路基高边坡生态防护技术集成研究提出展望,为黄土地区生态修复及黄土路基边坡绿色防护研究提供参考。The unique geological conditions and soil mechanics characteristics of the Loess Plateau give rise to significant landslide challenges in loess areas.The ecological protection(restoration) of transportation infrastructure in loess areas,particularly high speed railway subgrade slopes,has emerged as a crucial research topic within soil and water conservation and engineering geology.Using the Xi'an-Yan'an HSR loess subgrade as a case study,this paper examines the progress,application scope,and future development trends of research on ecological protection(restoration) of loess subgrade slopes from three perspectives:the disaster-causing mechanism in loess area,protective measures for loess subgrade slopes,and ecological restoration technology in loess areas.It delves into the specific slope protection technologies implemented for Xi'an-Yan'an HSR,covering engineering,biological,and drainage measures.It also proposes the potential for an integrated study on ecological protection technology for high slope of loess subgrade,offering insights for the future study on ecological restoration in loess area and green protection of loess subgrade slopes.
