【摘要】 采用模拟试验的方法探讨了在各种污染环境因素影响下(清水、不同化学溶液、不同浓度等)水泥土力学特性在不同龄期的表现,分析了其相应的荷载位移曲线变化,得出了水泥土在各种污染环境下的抗压强度与侵蚀历时的关系,结果表明硫酸对水泥土的侵蚀作用显著,污染环境中的化学成分和浓度对水泥土的抗压强度有着重要的影响。更多还原

【Abstract】 In order to simulate and study the erosion effect on cemented soil under environmental contamination,a series of unconfined compression tests were conducted on the cemented soil samples which were cured under various environmental conditions,including clean water,and H2SO4,NaCl,NaOH solutions with different concentrations.It was shown that the compression strength of the cemented soil varied with not only the curing time but also the contaminated types and the concentrations.The strength decreased in a high concentrated acid solution,thus the erosion effect on the cemented soil must be taken into account in engineering practice.更多还原
