A Mechanism Analysis of Pile-Soil Interaction of Micro-Pile in Building Heightening and Transformation

Abstract:

Based upon the characteristics of micro-pile in building heightening and transformation (mainly including the mechanism of the press injection increasing the bearing capacity , the rigid connection between micro-pile and its original foundation), through the analysis of its load characteristics in building heightening and transformation, using the theory of pile foundation constructed in reverse order, then the mechanical mechanism of micro-pile and original foundation is studied and the analysis method of soil-pile-foundation (cap) interaction by considering pile tip penetration displacement and soil compression between pile shafts is demonstrated.
