【摘要】 根据盐渍土的物理化学性质,采用掺入不同比例石灰或水泥的方法进行改性处理。经击实、抗剪和抗压强度试验结果表明,盐渍土掺入石灰或水泥改性后,混合料的最大干密度、最优含水率、强度指标等均有增加,特别是内聚力迅速增长。研究表明,盐渍土混合料的性状得到了明显改善,改性后的混合料可用于修建盐田埝堤类相关工程。更多还原

【Abstract】 To improve properties of saline soil,different proportions of lime or cement was mixed with saline soil according its physical and chemical properties.By shot-solid testing,anti-shear strength testing and anti-press strength testing,the results show that the maximum dry-density,the optimum water-ratio and strength of mixture were all increased,in particular,the cohesion was rapidly improved.The properties of the mixture of soil-cement or soil-lime are greatly improved,and they can be used to construct the bank of salt field.更多还原
