Each of the counterweights is formed of a bar element, having a constantsection throughout most of its length and being obtained by cutting to size a bar of indefinite length.
对每个配重组成一个酒吧的环节，通过其大部分长度不变部分和被切割的大小有一个无限长的棒，获得。

The results show that the tension bearing capacity of DX pile is apparently higher than that of the pile with constantsection, and the curve of load-displacement of DX pile is slowly varying.
结果表明，DX桩的抗拔承载力明显大于同等条件下的等截面桩，且DX桩的荷载-上拔位移关系呈缓变形；
