摘　　要：以郑西客运专线DK297+183至DK298+420的黄土路堑高边坡为试验段,探讨了采用工程防护与植被防护相结合的方法对黄土路堑高边坡进行防护的可行性,从边坡稳定和坡面植被根系特性两个方面分析了黄土路堑高边坡的适宜坡型,在此基础上进行了植被防护试验。试验结果表明,采用合理坡型,在坡面形成适宜植物生长的土壤环境,并进行植物的合理配置,该植被防护技术可应用于黄土路堑高边坡的防护且有利于植被恢复。By selecting the loess cutting high slope in Zhengxi passenger dedicated line DK297 ＋ 183 to DK298 ＋420 as a test section, the feasibility of using comprehensive measures combining engineering protection with vegetation protection in protection of loess cutting high slope was discussed. The slope types were analyzed according to slope stability and root characteristics of slope vegetation, and then the vegetation protection field tests were carried out. Tests results show that, the soil environment suitable to vegetation planting can be formed on the slope surface with adoption of suitable slope type, and the vegetation protection technology can be used in protection and revegetation of loess cutting high slopes on the basis of appropriate plant arrangement.
