摘要:
为了减少成品油管道事故影响,更好地掌握成品油在土壤中的流散规律,搭建了室内可视化实验装置,基于数字图像处理技术,建立了难以实时测量的柴油饱和度与方便获取的HSI颜色模式各分量之间的函数关系,并通过采样实验进行了验证。结果表明,H(色度)和S(饱和度)可以作为判断多孔介质内是否含油的指标;通过S在低饱和区对油饱和度表征精度可达3.12%;通过I(亮度)在高饱和区对油饱和度表征精度在±2%以内。建立的动态、实时、非侵入式的土壤内部成品油运移的可视化手段,可为泄漏过程演化提供支持。研究成果弥补了国内油品在土壤中泄漏扩散可视化方面的技术不足,对于有效控制成品油引起的环境污染问题、减少油品泄漏带来的危害具有重要意义。
