During the acceptance of bridge engineering piles,it is necessary to determine their bearing capacity to ensure structural safety.Compared to conventional testing methods such as pile loading and anchor pile,the self-balancing method of pile foundation has advantages such as simple operation,no site restrictions,reliable results,and low comprehensive testing cost.In the process of testing,the slow maintained load method was used to determine whether the grading loading and unloading,displacement observation,and stability standard indicators meet the conditions.The final loading capacity meets twice the characteristic value of the designed single pile bearing capacity,and the vertical compressive bearing capacity test of the single pile is completed
