桩自平衡测试技术

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。

PILE SELF-BALANCING TESTING TECHNOLOGY

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.
