摘　　要：提供一种简便、实用的土壤腐蚀性评价方法,以解决因土壤中存在砂石阻隔电子的移动,使电阻率及氧化还原电位测量出现较大偏差,从而影响土壤腐蚀性评价的技术问题。结合甘肃地区4个750kV变电站的现场检测实例表明,采用本方法所得土壤腐蚀性结果与现场腐蚀速率测试结果相吻合,验证了该评价方法的效果。lt aims to provide a simple and practical evaluating method of soil corrosion. The method can solve the affecting soil corrosivity evaluation technical problem that measuring of resistivity and redox potential showed a larger deviation because of gravel present in soil blocking movement of electrons. At the same time,four 750 kV substation in Gansu field detection examples show that soil corrosivity results of adopting the new method con-sistent with the results of field corrosion rate testing,which verify effectiveness of the evaluation method.
