摘　　要：该文依据HKFZ-AB450(250)空心方桩和PHC500AB100管桩在滨海吹填场地的试验,对比分析了两种桩型的单桩竖向抗压承载力、单桩水平承载力、造价及沉桩对消除地基土液化方面的数据,总结了两种桩型适宜性,对以后两种桩型的应用有借鉴意义。According to the tests of HKFZ-AB450（ 250） hollow square pile and PHC500AB100 pile in the castal blast-filled ground,this paper comparatively analyses on the data for eliminating foundation liquefaction by vertical bearing capacity of single pile,horizontal bearing capacity of single pile,cast and pile sinking of the two types piles. This paper summarizes the suitability of the two types piles,and it has reference for the two types piles applicated in the future.

关 键 词：空心方桩 PHC管桩 单桩竖向抗压承载力 单桩水平承载力 液化 经济性
