摘　　要：通过原状土、预钻孔夯扩挤密地基、混凝土桩、多桩型复合地基(由挤密桩及混凝土桩两种增强体组成)的载荷试验,及桩身应力与基底土压力量测等,对多桩型复合地基在自重湿陷性黄土场地的应用进行了系统的试验研究,为该场地高层建筑地基选型提供了依据。Through load test on Undisturbed soil, pre-drilled rammed compaction, concrete piles,multi-pile composite foundation（It is composed of compacted pile and concrete pile）,and measurement of pile stress,base earth pressure,a systematic experimental study was carried out on application of multi-type-pile composite foundation in self-heavy collapsible loess ground,it provides the basis for the selection of high-rise building foundation.
