摘　　要：自平衡试桩法是检测单桩竖向抗压极限承载力的一种试验方法。荷载箱的埋设位置是检测成功与否的重要因素之一。结合工程实例,就采用自平衡试桩法确定荷载箱埋设位置的问题进行探讨和总结,供同行参考。The self-balanced pile testing method is a testing method to detect vertical compression resisting limited capacity of single pile.The buried positions of load boxes are one of important factors for successful detection or not.This paper in combination with project examples probes and summarizes issues concerning determination of the buried positions of load boxes by self-balanced pile testing method to provide a reference for the industry.

关 键 词：自平衡试桩法 单桩竖向抗压极限承载力 荷载箱 桩基 平衡点
