摘要
对埋地燃气管道周边土壤的基本理化数据进行了因子分析,将9个检测变量归纳为4个公共因子。研究结果表明,土壤各方面的性质对于土壤腐蚀的重要程度不同。在进行多因素评价时,应选取含盐量、含水量、自然腐蚀电位、氧化还原电位以及土壤电阻率作为主要考察因素,而经常作为主要评价因素的pH值和杂散电流则可不用考虑。
Basic physical and chemical data of soil around buried gas pipeline is factor analyzed,and 9 check variables are reduced to 4 common factors.Research results show that different behaviors of soil have different importance to soil corrosion.It is considered that salt content,water content,natural corrosion potential,redox potential and soil resistivity should be selected as major checking factors,and pH value and stray current which generally being taken as main factors may not be considered when carrying out
