| 摘 要： | 人工挖孔桩在挖孔后，孔壁周围土体将会产生应力集中。利用弹性理论，推导了孔壁周围土体的应力计算公式，并用莫尔—库仑极限平衡准则对孔壁稳定性进行判别。

| Abstract: | After construction of manually-excavated hole piles have been finished, the stress concentration in periphery soil of hole-wall will be produced. Based on elastic theory, the stress calculation formula for the periphery soil of hole-wall can be deduced, and hole-wall stability will also be determined by the Mohr-Coulomb Criterion. |

| Keywords: | manually-excavated hole piles stability stress concentration |
