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
