摘　　要：为了验证数值模拟软件研究埋地管道阴极保护及其干扰相关规律的可行性和准确性,建立了室内土壤模拟溶液模型和室外埋地环道模型,开展阴极保护实验。其中,室内模型实验通过改变阳极位置获得了2组显著不同的电位分布,而室外环道模型通过电缆连接改变管道和接地系统的电连续性。采用数值模拟软件进行电位分布计算和验证,其结果与电位测量数据基本一致。进一步通过软件对室外环道接地极排负实验的3种施工方案进行了数值模拟计算,优选出最佳方案。In order to verify the accuracy of numerical simulation software applied to cathodic protection and its interference, the physical models in laboratory and field model have been established. The position of anode in lab can be easily changed to get two kinds of different potential distributions. The constitution of the pipe and grounding system can be changed by cable connect- ing in the field model. The results of numerical simulations are consistent with the measured data in the experiment. Furthermore, the optimal plan of the grounding system for controlling negative interference has been selected by simulation of the three designed plans.
