The ultimate flexural bearing capacity test was carried out through a total of 27 root specimen of the heart reinforcement pile, the steel pipe + heart reinforcement pile, the steel pipe + H section steel pile. It wasfound that the heart reinforcement pile ultimate flexural bearing capacity is low and that the failure was of brittle type, while the steel pipe + heart reinforcement pile and the steel pipe + H section steel pile show a higher bearing capacity and was of better ductility performance. Through the load-displacement curve, the heart reinforcement ile under loading is divided into specimen bite stage, elastic stage, elastic-plastic stage and failure stage, while the steel pipe + heart reinforcement pile and the steel pipe + H section steel pile can be divided into specimen bite stage, elastic stage, elastic-plastic stage and strengthening stage. The ultimate flexural bearing capacity for steel pipe + heart reinforcement pile can be regarded as that of steel pipe concrete pile multiplied by an increase coefficient of 1.2.
