对于大郎河渡槽这种单桩承载力较高的桩基,只要合理地选择荷载箱型号及安装位置,采用自平衡法检测基桩竖向抗压承载力是可行的。大郎河渡槽工程区共布置两组试桩,按照设计参数计算的单桩抗压承载力分别为26500kN和36000kN,按照自平衡法试验实测单桩竖向抗压承载力平均值分别为37630kN和53837kN,由此可以看出,大郎河渡槽桩基设计成果是安全可靠的。 For the pile foundation with high bearing capacity of Dalanghe aqueduct, it is feasible to detect the vertical compressive bearing capacity of foundation pile by self-balance method, as long as the load box model and installation location are reasonably selected. According to the design parameters, the compressive bearing capacity of single pile is 26500kN and 36000kN, respectively. According to the self-balance test, the average vertical bearing capacity of single pile is 37630kN and 53837kN, we can see that the design results of Dailanghe aqueduct pile is safe and reliable.
