对钱江通道及接线工程南接线段01标段U型槽3根位于粉土地层中的抗拔桩进行了现场抗拔承载力试验。3根试桩均为工程桩,在试验荷载超过预估承载力后试验即停止。试验结果表明,这3根试桩的最大抗拔力均大于抗拔桩单桩轴向受拉承载力极限值的计算值。试验结果可以为相关设计规范的修编提供参考。
On the Qianjiang Channel and the South Section of the connecting section 01 section of the U-slot 3 in the silt strata in the anti-uplift pile site pull-out capacity test. The three test piles are all engineering piles, and the test stops after the test load exceeds the estimated bearing capacity. The test results show that the maximum pull-out force of the three test piles is larger than the calculated value of the ultimate tensile load-bearing capacity of the pile. The test results can provide references for the revision of relevant design specifications.
