摘　　要：通过室内模拟试验,测定了不同含量NaOH污染土的物理指标和pH,对比分析了NaOH污染土各项指标与侵蚀介质含量之间的变化关系,揭示了X70钢在碱性污染土中的腐蚀行为和腐蚀规律,研究了X70钢的腐蚀速率与污染土的腐蚀参数之间的关系与规律,利用回归分析方法建立钢在污染土中的腐蚀速率与污染土基本指标的关系模型。To study the effect of alkaline soil pollution on X70 steel, the physical index and pH of soil polluted by NaOH with different content were tested in laboratory. The relationship between the index of NaOH polluted soil and the content of corrosive media was analyzed comparatively. And the corrosion behavior and law of X70 steel in alkaline polluted soil was revealed. The relationship between the corrosion rate of X70 steel and the corrosion parameters of polluted soil was studied. A relational model of corrosion rate of X70 steel and corrosion parameters of polluted soil was built by regression analysis method.
