摘　　要：通过对某高层框架结构多桩型复合地基设计,讨论了多桩型复合地基的承载力和沉降计算方法,对两种桩型联合应用的设计方案选择进行了分析,并对最终复合地基的承载力及地基变形进行了计算。计算结果与现场实测一致,满足工程精度要求。说明在某些工程地质条件下联合运用两种不同性状的桩型,可以获得更加合理的地基处理效果。Through designing a high-rise frame structure with muhi-type-pile composite foundation, bearing capacity and settlement calculation methods of multi-type-pile composite foundation are discussed, and design scheme selection of two type piles with different characters is analyzed. The results of final composite foundation bearing capacity and settlement calculation based on the engineering practice are consistent with that of the field test and meet the need of the engineering accuracy. The results show that in some engineering geological conditions, the combined use of two type piles with different characters can achieve more reasonable treatment effect of the foundation.
