摘　　要：简述了桩自平衡测试法的原理、荷载转化方法,探讨了上段桩、下段桩、单桩极限承载力确定存在的问题。对青岛市某工程的桩自平衡测试结果表明,桩自平衡测试技术具有具有试验装置简单、投资较低、缩短测试时间、测试结果可靠等优点,广泛应用于钻孔灌注桩,人工挖孔桩、沉管灌注桩,是一种很有发展前景的桩基测试技术。This papers brief test method of pile self-balancing and load conversion method, explore the identified problems of the upper pile, the lower pile and pile ultimate bearing capacity, the pile self-balancing test results of a Qingdao project show that the pile self-balancing testing technology Has the advantages of a test device simple, low investment, test time reduction, test results reliable, etc,widely used in bored pile, hand-dug pile, filling pile. It is a promising pile testing technology.
