摘要
依据福州市某超高层建筑试桩工程项目特点,通过设置长、短桩分别进行抗拔静载试验并对抗拔承载力进行扣减的方式,得到该项目大直径灌注桩在有效桩长范围内的单桩竖向抗拔承载力,经分析,此方法准确可行。
According to the properties of a pile testing project for ultrahigh-rise building in Fuzhou,several uplift static load tests were carried out separately for the long testing piles and the short ones with deduction of uplift bearing capacity. The vertical uplift bearing capacity of single pile with large diameter cast-in-place pile in the effective pile length range is obtained. It is concluded that the method is accurate and feasible.
