| 摘 要： | 为了解石油污染对土的压实特性的影响,利用室内击实试验,以原油、柴油和水为介质,得到了单一液体介质和油水混合介质时土的击实曲线。结果表明:石油代替水作为壤粘土孔隙流体,其击实曲线无明显峰值,干密度随含油率增加略有增大但远小于无污染土的最大干密度。油水混合作为孔隙流体,随含油率的增加,原油污染土壤的击实曲线由钟型、双峰型转向无明显峰值曲线,出现类似高液限粘土压实特性;柴油污染土的击实曲线由尖锐型转变为无峰值型;最优含水率均减小,最大干密度随含油率变化规律与油品性质有关。提出了"油膜润滑"的新观点,可较好地解释石油污染壤粘土击实曲线的变化规律。

| Abstract: | Influence of oil contamination on compaction properties of soil is analyzed in this paper. Standard compaction tests on loamclay with single liquid medium such as crude oil,diesel,water and oil-water mix medium are performed. When petroleum replaces water as hole fluid,the compaction curves have no obvious peak value,and its dry density increases slightly along with the increasing of oil content,even it's far less than the maximum dry density of soil without oil pollution. Adding water to the oil contaminat... |
