通过一系列室内固结压缩试验，分析了养护龄期及含盐量对灰土压缩性的影响，并从微观结构性上给出了合理的解释。试验结果表明：2种灰土的工程性能均随着养护龄期的增加而改善，尤其在40 d内改善较为明显；二八灰土的压缩系数随着硫酸盐含量的增加而不断增大，含盐量在2％内较为明显，水泥灰土的压缩系数随着含盐量的增加呈现先减小后增大的趋势，其含盐量界限在7％左右。所得结果对灰土在硫酸盐盐渍土地区工程施工检测及质量控制具有一定的实际意义，可为2种灰土处理硫酸盐盐渍土地基的工程实践提供借鉴和参考。

T hrough a series of consolidated compression tests of lime‐soil ,the effects of the curing age and salinity of lime‐soil on its compressibility were investigated , and the reasonable explanation on the microstructure was given . The test results show that the engineering properties of the two kinds of lime‐soil are increased when the curing age is increased ,which is changed obvious especially in 40 d .2 ∶ 8 lime‐soil compression coefficient increases with its increasing sulphate content , w hich is more obvious w hen sulphate content is 2% . How ever , Cement lime‐loess compression coefficient first decreases and then increases with its increasing salinity at a limit of about 7% .The obtained results have a certain practical significance on the engineering construction detecting and quality control in sulphate saline soil areas , and can provide references for the engineering practice of the two kinds of lime‐soil treated sulfate salty foundation .
