摘　　要：淄河滩陈化油污土层是引起大武水源地东部地区地下水污染的主要污染源之一 .通过对油污土层采取原状土柱样 ,在室内进行了旨在模拟大气降水作用时的残油释放试验研究 .结果表明 ,平面上油污土层多年平均可淋出油量 144 9 2 6mg m2 ,油污土层的存在不仅使大量的地下水遭到石油类物质污染 。The layer of crusted residual oil in Zihe Riverbed is one of the main contamination sources that cause the pollution of groundwater in the east part of Dawu water supply. By taking an undisturbed column of oil contaminated soil,an experiment of residual oil release indoor in order to simulate the rainfall action on residual oil release.the authors,was finished. The results indicate that 1449.26?mg oil were eluviated per m\+2 horizontally under the action of perennial average precipitation, and the oil contaminated soil not only polluted a great deal of groundwater but also is a long term contamination source.
