| 摘 要： | 根据充电法原理,结合模型桩试验,分析了钢筋笼周围的充电电场特征,结果表明钢筋笼的底端对应于电位梯度曲线的极小值点及电位曲线的拐点。以此研究结果为基础,提出了利用钻芯孔来检测成桩后钢筋笼长度的方法。某桥的应用表明,该方法简便、实用、可靠。 |

| Abstract: | Based on the principle of the 'mise-a-la-masse' method and the result of model pile testing, this paper deals with electric field characteristics around the reinforcement cage. Tests reveal that the bottom of the reinforcement cage corresponds to the minimum of the electric potential gradient curve and the inflexion of the electric potential curve. A method for reinforcement cage length detection in the core drilling hole is accordingly presented. Practice shows that the method is convenient, practicable and credible. |
| Keywords: | reinforcement cage length electric potential gradient electric potential core drilling hole |
