摘　　要：从复合地基承载力、工后沉降量并考虑成桩效应综合分析,提出相应的CFG桩复合地基桩间距设计计算方法,在进行复合地基桩间距的设计时,应保证复合地基承载力满足设计要求,加固后地基土的工后沉降量应满足规范要求;同时,为确保施工质量,还应充分考虑打桩带来的不利影响。From bearing capacity of compound foundation, settlement after construction and consideration of synthetic effects of finished pile, the paper poses appropriate calculation methods for design of interval between CFG piles of compound foundation. At the time of design of interval between piles of compound foundation, it should be accomplished to ensure bearing capacity of compound foundation to satisfy demands for design, the soil settlement after foundation reinforcing ought to meet specification requirements. At the same time, so as to ensure construction quality, the unfavourable influence brought about by pile driving should be fully thought over.
