摘　　要：通过太原东山深厚黄土地区某工程采用钻孔夯扩挤密桩进行处理,有效地消除了黄土的湿陷性,提高了地基承载力,减少了建筑沉降量,建筑沉降均匀,综合说明钻孔夯扩挤密桩是一种行之有效的地基处理方式,尤其在深厚黄土湿陷地区,针对小高层建筑地基处理的优势更加突出。The paper applies drilled-hole dynamic-compaction pile to deal with the engineering in deep loose area of Dongshan in Taiyuan city,effectively demolish the loose collapsibility,improves the foundation bearing capacity,reduces the building settlement,keeps the even building subsidence,comprehensively illustrates that:the drilled-hole dynamic-compaction pile is a feasible foundation processing method,especially in deep loose collapsible area,it has optimum advantages for processing high-rise building foundation.
