摘　　要：上海浦东国际机场二期航站楼为低承台群桩基础。针对地基土层中持力层落差大及满足主体工程按期开工的工期要求,为避免密集群桩在沉桩过程中,由于挤土效应而影响沉桩质量和桩位精度,论述了选择合适的桩型、沉桩流水、桩位复测时机及长桩在施打过程中防桩顶破碎等技术措施。Old English was not an entirely uniform language. Not only are there differences between the language of the earliest written records (about A.D. 700) and that of the later literary texts, but the language differed somewhat from one locality to another. Four Principal dialects were spoken in Anglo-Saxon England: Kentish, West Saxon, Mercian, and Northumbrain. This paper will explore the classification, the distribution and the features of old English dialects.

关 键 词：密集群桩 地基土层 挤土效应 桩型沉桩流水 桩位 桩顶保护
