［摘要］运用自平衡试桩法对贵阳奥体中心主体育场工程32根桩基进行检测，解决了工期短、场地紧张、荷载大的基桩检测难题。试验结果表明，达到设计荷载时桩基的位移值均较小，最大位移仅为6.01mm，基桩基本处于弹性变形阶段，远小于《建筑基桩检测技术规范》(JGJ106—2003)中的破坏状态限值。侧摩阻力值还处于线性增长阶段，且数值十分可观，据此有望解决贵州省目前桩基承载力侧摩阻力不能充分利用的问题。

Abstract:The self-balanced loading test was conducted to test 32 piles of the main stadium in Guiyang Olmypic Sports Center. The problems of the short construction period, not enough site and healy load were solved. The results show that the displacement values of piles are always small, the maximum displacement is only 6.01mm when reached the pile design load，and the pile is basical in elastic deformation stage，which is far less than the destruction of the state limits in Building foundation inspection technical specification(JGJ106—2003). The shaft friction value is still in the linear growth phase. The self-balanced method may resolve the problem that the shaft friction is not ful used in Guizhou Province.

Keywords:self-balanced method; Guiyang Olympic Sports Center; shaft friction; pile
