The Experimental Study on Influence of the Plate Space on Uplift Failure Mechanism of the Concrete Expanded-Plate Pile under Vertical Tension in Undisturbed Soil

Abstract

Based on the existing theories about the concrete expanded-plate pile and through small-scale model test with undisturbed soil, this article studies the influence of plate space on the uplift failure mechanism of the soil surrounding the concrete expanded-plate pile, and after analysis by the finite element software, the conclusions were compared with those of experimental research. which provides a reliable theoretical basis for design, calculation and engineering application of the bearing capacity of the concrete expanded-plate pile, thus laying a good foundation for its application.
