| Abstract: | Because of the advantages of simple construction, large bearing capacity increases,the post grouting technology has been widely used. With the practical project, the paper introduces the field test study of grouting in different length of bored pile,analyzes the characteristics of bearing deformation. The application of post grouting technology is successful in practical project. |
