土壤腐蚀是造成牙哈装车南站储罐底板腐蚀的重要因素,影响土壤腐蚀性的因素有很多.一旦储罐底板腐蚀穿孔,将带来巨大的经济损失,造成严重的环境污染,甚至引起火灾等严重后果.若采用单因素分析法不能综合考虑所有影响因素,采用主成分分析法(PCA)对站场内土壤腐蚀等级进行评价,去除重复数据和测量误差较大的数据,找到影响因素中的关键因素,有效评价土壤的腐蚀等级.通过测试牙哈装车南站土壤样品的理化性质,利用SPSS软件对具体试验数据进行主成分分析,实测结果主成分分析法对评价土壤腐蚀性是很有效的.

Soil corrosion is an important factor to the Yaha loading station tank floor corrosion,there are many factors affectting soil corrosion.Once tank floor suffers corrosion perforation,huge economic losses will happen which can cause serious environmental pollution,and even cause serious consequences such as fire.In the single factor analysis method,not all influencing factors can be considered.Using principle component analysis (PCA) to evaluate soil corrosion grade,to remove the duplicate data and error measurement data and to find the key factors in the influence factors,The evaluation of soil corrosion level can be effective.By testing the physical and chemical properties of soil samples of Yaha loading station,using SPSS software for principal component analysis of Yaha loading station,the final calculation results were compared with the measured results,PCA for evaluation of soil corrosion was effective.
