Concrete expanded pile represents a new type of variable section pile foundation. In this article, with the test method of small-scale half-section model pile with undisturbed soil, the whole process from soil loading to destruction was observed in order to study the influence of bearing disc position on soil failure state around the pile. In this article, the influence of disc position on horizontal bearing capacity and soil failure state of concrete expanded piles is studied, which will improve the design theory of concrete expanded piles, lay a foundation for the improvement and innovation of test methods, and provide a reference for the research and development of pile foundations in oceanographic engineering.
