| 摘 要： | 基于长输管道658处土壤取样点的腐蚀等级及变化趋势,选取30处典型土壤腐蚀点开展埋片试验,建立土壤腐蚀数据样本。采用BP神经网络评价法,进行多因素分析30处埋片点的测试结果,并预测其他628处取样点的土壤腐蚀特性。该方法可为今后长输管道土壤腐蚀特性分析提供依据和标准。

| Abstract: | Based on long-distance pipeline corrosion level and trend of 658 soil sampling points, 30 typical soil erosion points were selected to carry out buried tests to establish soil erosion data sample. BP neural network evaluation method was used to carry out multivariate analysis of test results to predict soil erosion characteristics of other 628 points. This method provides the basis and standard for analysis of long-distance pipeline corrosion properties in soil in the future. |
