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。 |

Abstract:
In a static loading test,the variation of axial force and the resistance of expanded plates are measured 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 of 50% in post-loading.
