This paper mainly introduces application of deep mixed pile,some conclusions are got in the period of pile s designing,construction,testing and effect.

The scheme of deep mixed pile and bolting-shotcrete for retaining and protecting foundation excavation has been used according to actual conditions of project.

The reinforcing method with deep stirring piles employs cement and raw lime powder as solidification agent, which are forcibly mixed with soft clay soil in the depth of foundation by deep stirring machine and create a compound foundation with certain strength as a result of a series of physical and chemical reaction during stirring.

Taking actual engineering as the example and according to geological exploration and analysis on, this paper determines the treating scheme of ground treatment with deep stirring pile, expounds its strengthening principle, design calculation and construction method.

Based on the measured data of more than 100 deep stirring piles in a certain project, combined with static loading test on over 20 piles, this paper deals with the feasibility of using the reflection wave method to detect the completeness of the deep stirring pile body.
