摘　　要：本文结合工程实例,分析土方开挖造成基桩偏斜的成因,采用低应变动测和孔内摄像技术准确评定桩身断裂情况,计算分析偏心荷载作用下基桩竖向承载力,为设计人员处理基桩偏斜事故提供有益的借鉴。Based on the concrete personification, the cause of pile eccentric by earthwork dig is analyzed, the pile flaw is appraised by low strain integrity testing and hole video monitor testing, the vertical beating capacity of eccentric loaded pile is calculated and analyzed. It is helpful for designer to conduct on eccentric accident of pile.

关 键 词：预应力混凝土管桩 基桩偏斜 孔内摄像 竖向承载力
