摘　　要：介绍自平衡测试结果向传统静载转换的方法,并对泥浆护壁成孔的钻孔灌注超长桩,提出了通过自平衡转换曲线判断极限承载力的方法。This paper presents the method for equivalently converting the data obtained from selfbalanced load test to those from the conventional static load test, and describes the way for determining the ultimate carrying capacity of the super long bored piles with pile holes protected by boring fluid through the conversion curve of the selfbalanced load test method.

关 键 词：超长桩 自平衡测试 桩侧摩阻力 极限承载力
