摘要
针对沿海回填超厚碎石土地基,结合工程实例,通过现场单点夯击试验、群点夯击试验,总结确定25 000 k N·m超高能级强夯的施工参数,通过不同的强夯能级组合及振动碾压,实现超厚碎石土地基的有效加固,满足地基承载力的设计要求,形成成熟的沿海回填超厚碎石土地基施工技术。
In view of the coastal backfill super thick gravel soil foundation,combined with the engineering example,through on-site single-point tamping test,group of tamping test,summed up to determine 25 000 k N·m high energy level dynamic compaction construction parameters and through different combination of dynamic compaction energy level and vibration compaction,the effects of super thick gravel soil reinforcement,meets the design requirements of bearing capacity of foundation,the formation of mature coastal backfill ultra thick gravel soil foundation construction technology.
