Abstract
The previous research results of the research group demonstrated that the plate position is the main factor affecting the uplift bearing capacity of the new type of concrete expanded plate pile (NT-CEP pile) group and the failure state of the soil around the pile. In this study, the visual half-section pile small-scale model of undisturbed soil tension test and ANSYS Finite Element Software comparative analysis two-pile small-scale test model and two-, four-, six-, and nine-pile models, which included the corner, side, and middle piles, were developed. The effect of the plate position on the displacement, stress, and bearing mechanism of the NT-CEP pile group under vertical tension was determined, which further improved the design concept of the NT-CEP pile group and provided strong theoretical support for its widespread application.
