摘要: 介绍武汉四新地区较常用的主要深层地基处理方法及其适用范围和优缺点,首次在武汉四新地区采用了钉形水泥土双向搅拌桩进行地基处理,通过大量的桩身标准贯入试验和室内无侧限抗压强度试验,对钉形水泥土双向搅拌桩的桩身强度性能进行了一系列分析,同时建立了桩身标准贯入击数、桩身无侧限抗压强度与桩体分段深度之间的数学关系式。

Abstract: The application, merits and demerits of deep foundation treatment in Wuhan Sixin region was introduced, then the application of T\|shaped Bidirectional Soil\|cement Deep Mixing Pile in this region was also introduced. Its strength was analyzed by SPT and unconfined compression strength test, meanwhile the equation between SPT's blow counts and pile's unconfined compression strength, depth of pile's segment.

Key words: T-shaped bidirectional soil\, cement deep mixing pile, strength, property, analysis
