摘　　要：通过对挤扩支盘桩的静载荷试验,由钢筋应力计测试出挤扩支盘桩的桩身轴力,支盘阻力的变化规律,分析竖向荷载作用下挤扩支盘桩的荷载传递机理和变形特性,结果表明挤扩支盘桩在加荷后期,支盘承担50%以上荷载。In a static loading test,the variation of axial force and the resistance of expanded plates are mea-sured by means of setting stress meter,from which the load-transferring mechanism and deformation behavior of vertically loaded squeezed branch pile are investigated and discussed.The results indicated that the expanded branches or plates support the vertical load in excess of50%in post-loading.
