通过大量的室内试验，对雅安地区过湿土掺加石灰、水泥和EN-1土壤固化剂后，对其含水量的损失规律和工程力学性质的变化规律进行研究，分析了各种改良土的工程性质与外加剂掺量、素土含水量以及龄期等因素之间的关系，并将各种改良土的技术参数进行了对比，试验结果表明：掺加水泥的改良效果优于石灰，配合新型的EN-1固化剂后的改良作用更显著。

Through large amount of indoor tests and against the overwet soil in Ya＇an Region mixing lime, cement and EN-1 soil stabilizer, the laws relating to loss of moisture content and change of engineering mechanical properties are studied; the engineering properties of various improved soil and the relationship between various factors such as additive content, moisture content and age of plain soil, is analyzed; and the technical parameters of the improved soil are compared. The test results show that the effect of improvement by mixing cement is superior to that by mixing lime and the improvement effect with new EN-1 stabilizer together is more outstanding.
