摘要
针对挖山填沟土方平衡形成和通过借方回填等形式形成的高填方地基,结合工程实例,通过原地面地基处理、分层回填、挖填交界面挖台阶、分层强夯处理等一系列加固技术,通过调整土方回填参数和分层强夯参数,并进行变化组合,对超高填方地基进行有效加固,使得加固效果、地基承载力和工后沉降均能满足设计要求,且具有快速、高效、安全和环保等特点。
According to the high fill foundation,based on engineering practice,a series of reinforcement technologies were adopted as foundation treatment,layered backfill,digging steps and layered dynamic compaction. According to adjusting the backfill and dynamic compaction parameters,the reinforcement result can meet the design requirement and it is fast,efficient,safe and environmental.
