摘　　要：黄土沟壑区超高填方的施工质量不易控制,往往工后沉降过大。采用小间距加筋土挡土墙对陕北某工程超高填方边坡进行了设计加固,经过现场精细施工把控,加固效果良好,工后沉降稳定。总结其设计施工经验,提出适合黄土沟壑区复杂地形条件下小间距加筋土挡土墙施工控制重难点,希望为黄土丘陵区超高填方建设提供参考经验。The construction quality of ultra-high fill in loess gully areas is not easy to control,and often the post-construction settlement is too large.Small-spacing reinforced earth retaining walls were used to design and reinforce the ultra-high fill slope of a project in northern Shaanxi.Through on-site fine construction control,the reinforcement effect is good and the post-construction settlement is stable.Summarizing its design and construction experience,the key and difficult points of construction control of small-spacing reinforced earth retaining walls under the complex terrain conditions in loess gully areas are proposed,hoping to provide reference experience for ultra-high fill construction in loess hilly areas.
