摘　　要：文章通过建立多点夯击模型,分析多点夯击下吹填路基加固效果的影响因素。研究结果表明:不同的夯击次序和夯击方式会对路基深部土体的加固效果产生影响;多点夯击下夯点间距越小时,夯间土的加固效果越好。研究结果为强化强夯地基处理设计提供参考。In this paper,the influencing factors of the reinforcement effect of the blown subgrade under multipoint tamping are analyzed by establishing a multi-point tamping model.The results show that different tamping sequences and tamping methods will affect the reinforcement effect of deep subgrade soil.The smaller the spacing of the ramming points under multi-point tamping,the better the reinforcement effect of the rammed soil.The research results provide a reference for the design of enhanced and high-compaction foundation treatment.
