| Abstract: | In the theoretical research of jacked pile,the first problem to analyze the penetration characteristics of jacked pile in the process of pile jacking is to clarify the penetration mechanism of jacked pile. Based on the analysis of penetration mechanism in the process of pile jacking,this paper summarizes and analyzes three theoretical analysis methods of pile jacking. They are circular hole expansion theory,strain path method and finite element analysis. This paper points out the shortcomings of the current research on the penetration mechanism of jacked pile and puts forward some suggestions and understandings on the penetration mechanism. Based on the traditional theory of hole expansion and the strain path method,it is suggested to analyze the nature of pile sinking mechanism of static pile based on the nonlinearity of soil,the interaction between pile and soil and the spatial characteristics. The summary of the theoretical research on the penetration mechanism of jacked pile can be helpful to estimate the construction impact range of jacked pile,so as to provide better reference for the design and construction of jacked pile and bring good economic benefits. |
