Analysis of Pile Stress during Static Pressure Pile Penetration

摘要

Static pressed pile in the sand is a complex process. In this paper, strain of each point in the process of model pile sinking was measured by lab model test, the relationship of stress and strain of piles and the corresponding stress coefficient are made by semi-numerical and semi-analytical mathematical methods, the distribution of confining pressure and friction are built, and the calculation of sinking pile resistance in the process of construction is given out. The result provides the directive reference for the design of static pressure pile.
