To resolve the problem of heavy self-weight, easy cracking and low load-bearing capacity of ordinary concrete poles, on the basis of centrifugal molding process, the optimal mix ratio of coarse aggregate UHPC was designed by adjusting the centrifugal speed, acceleration and time. Six UHPC annular poles with coarse aggregate were made by variable speed centrifuge, thus enhancing the production efficiency. The failure mode, crack resistance and bearing capacity were investigated by four-point bending static loading with steel fiber content and reinforcement ratio as parameters. The test results show that the failure mode of the pole can be divided into three stages: elasticity, crack development and failure. With the increase of steel fiber content, the number of main cracks of the pole gradually decreases, while the number of minor cracks increases accordingly. Steel fiber hindered the development of cracks to a certain extent, and its flexural capacity increased by 42.6%. With the increase of reinforcement ratio, the number of main cracks of the pole is not much different, but the length and width of the cracks are obviously reduced. The resistance to deformation is strengthened, and the flexural bearing capacity is increased by 63.8%. The calculation results of flexural bearing capacity of RPC pole is close to the experimental value, but relatively safe and conservative. However, with the increase of reinforcement ratio and steel fiber content, the theoretical calculation value is closer to the experimental value.The calculation method of the flexural bearing capacity of the activated powder concrete pole is similar to that of the test results.
