论文摘要
近年来，不同烃对土壤的污染引起了岩土工程师的注意。但是，据我们所知，尚未进行系统的研究来研究气体油和苯污染对沙质土壤岩土技术特性的影响。因此，本研究使用多种实验室测试（例如直接剪切，压实和渗透率测试）研究了气体油和苯污染对两种沙质土壤岩土技术特性的影响。压实测试结果表明，在油污染的样品中，最佳水分含量下降。否则，最大干密度最多增加了5％的油含量，然后通过向沙质土壤中添加油来降低。直接剪切试验表明，油污染后的凝聚力增加，摩擦角降低。渗透率测试的结果表明，污染导致沙质土壤的渗透性降低，而变化是油含量和油的粘度的函数
In recent years, contamination of soils by different hydrocarbon has drawn the attention of geotechnical engineers. However, to our knowledge, no systematic studies have been conducted to investigate the effects of gas oil and benzene contamination on the geotechnical properties of sandy soils. Therefore, the present study investigates the impact of gas oil and benzene contamination on the geotechnical properties of two kinds of sandy soil using several laboratory tests such as direct shear, compaction, and permeability tests. The compaction test results showed that optimum moisture content declined in oil-contaminated samples. Otherwise, the maximum dry density increased up to 5% oil content and then decreased by adding oil to the sandy soils. The direct shear test indicated that cohesion increased and friction angle decreased after oil contamination. The result of the permeability test revealed that contamination caused a decrease in permeability of sandy soil and the change was a function of oil content and viscosity of oils
