摘　　要：简述了自平衡测试技术的基本原理,结合松花江大桥上的工程实例,简单介绍了试桩设计与施工,通过试桩测试结果分析取得该桩基桩端阻力与桩侧摩阻力关系及极限承载能力,试验结果表明该方法具有较高的精度,有关数据可为设计单位优化桩基设计提供可靠的依据,并为同类测试提供有益的借鉴。With the Songhua River bridge as a practical example, the basic principles of the self-balancing measuring and testing techniques are introduced in the paper, with the design and construction of the test pile briefly dealt with. By analyzing the measured results of the test pile, the pile-end resistance, pile-side resistance and the ultimate bearing capacity are acquired. The result of the test proves that the method has quite good accuracy. All the related data form a reliable basis for design units in optimizing the design of pile foundations, as well as serve as a useful reference for similar projects in the future.
