摘　　要：以某沿海二级公路建设项目为背景,介绍两种常用的复合地基加固软土地基处理方案。在阐述长螺旋钻孔压灌桩和钉形双向水泥土搅拌桩两种桩体成桩工艺流程和质量控制要点的基础上,对两种桩体在加固软体地基方面的优缺点进行对比分析,最终确定该项目软土地基加固方案为长螺旋钻孔压灌桩。Based on a coastal secondary highway construction project,this paper introduces two commonly used composite foundation treatment schemes for soft soil foundation reinforcement.Based on the introduction of the pile forming process and quality control points of the long spiral bored pile and the nail shaped bidirectional cement soil mixing pile,the advantages and disadvantages of the two kinds of piles in the reinforcement of soft soil foundation are compared and analyzed,and it is finally determined that the reinforcement scheme of the soft soil foundation of the project is long spiral bored pile.
