摘　　要：以南龙高速公路为例,针对施工阶段纵面抬高,结合实际拟定4种地基加固方案进行比选,择优选取气泡轻质土路堤加固方案。结果表明,该方案保证路基稳定,缩短施工工期,减少施工难度,取得了良好的经济效益。Taking Nanlong expressway as example,aiming at the construction stage and vertical elevation,four feasible foundation reinforcement schemes were compared,From the in-depth comparison demonstration,the bubble lightweight embankment reinforcement scheme is selected as the best one.This scheme can ensure the stability of subgrade,shorten construction period,reduce the difficulty of construction,and achieve good economic benefits.
