Abstract:Based on conventional balled pile and wedge pile, a new type pile: balled wedge pile was developed. The new balled wedge pile can improve shaft friction and tip resistance, and reduce the influence of negative skin friction. In this paper, the accuracy of FLAC 3D model is verified with field test results. Subsequently, the numerical model was used to study the behavior of balled wedge pile, conventional balled pile, wedge pile and uniform section pile with the same concrete volume. Furthermore, the behavior of balled wedge pile group was studied in terms of influencing factors such as pile spacing, pile position, stiffness of pile end soil, and the diameter of enlarged pile head. The numerical results show that the uplift capacity of balled wedge pile is similar to balled pile, and it increases with increasing pile spacing, increasing stiffness of pile end soil, and increasing diameter of the enlarged pile head. ? 2011 Taylor & Francis Group, London.
