Abstract
The paper presents research results into the influence of motor fuels on the shear strength of coarse-grained soil. The soil was classified following the unified soil classification system PN-EN ISO 14668-1 as saGr. The soil samples were artificially contaminated with three percentage ratios of motor fuels 5, 7.5 and 10% in relation to the dry mass of the soil skeleton. The test results have shown that motor fuel contamination significantly impacts the tested soil's mechanical properties. Increasing the content of impurities causes a significant decrease in shear strength parameters. For soil contaminated with 5%, 7.5% and 10% of motor fuel, i.e. gasoline or diesel, the angle of internal friction decreased by 8%, 15% and 20%, respectively. Along with the impurities increase, the soil's ultimate bearing capacity, calculated following EC-7, showed a dramatic decrease. The decrease was 40%, 57% and 66% respectively.
本文介绍了汽车燃料对粗粒土抗剪强度影响的研究成果。土壤按照统一的土壤分类体系PN-EN ISO 14668-1分类为saGr。土壤样品被人工污染，分别用相对于土壤骨架干质量的5%、7.5%和10%的三个百分比比例的发动机燃料污染。试验结果表明，燃油污染对试验土的力学性能有显著影响。随着杂质含量的增加，抗剪强度参数显著降低。当汽油、柴油的掺量分别为5%、7.5%和10%时，土壤的内摩擦角分别降低8%、15%和20%。随着杂质的增加，根据EC-7计算的土的极限承载力呈现出急剧下降的趋势。降幅分别为40%、57%和66%。
期刊介绍：
Rocznik Ochrona Srodowiska publishes articles concerning widely understood environmental engineering and environmental protection. We are interested in manuscripts covering technologies and equipment used in water treatment, wastewater treatment, air purification, thermal utilization, processing and use of waste. But we publish also papers concerning sanitary installations, environmental law, education and health protection in relation to the protection of the human environment.
