摘　　要：本文结合石济客专济南黄河大桥工程，试桩采用自平衡法检测单桩竖向抗压极限值，并与单桩竖向抗压设计承载力理论值比较。为了与传统静载试验的结果进行对比，还将自平衡法测试所得的上下段桩的荷载-位移曲线转换为桩顶荷载-位移曲线。This paper, combining with Shijiazhuang-Jinan pa- ssenger dedicated line engineering on the Yelow River Bridge in Ji＇nan city, the pile adopted self balanced detection method and single pile vertical compressive bearing capacity, and is compared with theoretical value of single pile vertical comp- ression design. In order to compare it with test results of tradi- tional static load, the author also convert the pile load-disp- lacement curve of self balance test to the pile top load -displac- ement curve.
