Besides, the reliability index is closer to objective practice of tension pile in comparison with the factor of (safety.)

此外，得出可靠度指标较安全系数更能符合抗压桩的客观实际。

According to the principle of the minimum potential energy the deformation of single tension pile and pile groups was analyzed using a modified variational approach.

根据最小势能原理，使用修正变分法来分析抗拔单桩和抗拔群桩的变形。

根据最小势能原理，使用修正变分法来分析抗拔单桩和抗拔群桩的变形。

The distribution of the earth pressure under raft is studied and discussed. In addition, the characteristics of the tension pile under the podium of the tall building is analysed.

还分析了筏底土压力的分布机理 ，探讨了影响桩间土分担荷载作用的因素。

The reinforcement scheme which add tension piles and shear walls in the garage was put forward. The calculation results show that the uplift load of the pile greatly reduced after adding shear walls.

提出了在地下车库内增设抗拔桩和剪力墙的加固方案，计算结果显示，增设剪力墙后桩基所受上拔力大幅度降低。

The results show that the tension bearing capacity of DX pile is apparently higher than that of the pile with constant section, 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；

In addition, there is a certain recovery of deformation for pile body and anchor steel under the forward tension condition after unloading.

另外，卸载后，在正的受拉状态下，对于桩体和锚杆钢筋，变形均有一定程度的恢复。

In addition, deep excavation can cause considerable tension force in the pile, which means that the reinforcing steel bars in the lower part of the pile should not be reduced at discretion.

此外，超深开挖可在桩身中产生较大的拉力，桩身中下部钢筋不能随意减少。
