水泥土由于其良好的性能，在工程中得到了广泛的应用。然而，实际工程中往往因场地条件的不同，会直接影响其加固效果。该文通过直接剪切试验和压缩试验，研究了水泥掺入比、水灰比、含水率等因素对鄱阳湖疏浚土的强度的影响。结果表明：水泥掺量，含水率，水灰比，养护条件等因素都对疏浚土的强度和压缩有影响。随着水泥掺量的增加抗剪强度逐渐增大，随着含水率的增大抗剪强度逐渐减小。对于相同条件下水泥土的最小压缩系数存在最佳水灰比。

Cement soil is widely used in engineering for good performance. However, different site conditions often directly affect its solidification effect in practical engineering.Based on direct shear test and compression test, the impacts of cement mix proportion, water cement ratio and moisture content on the dredged soil strength of Poyang lake are studied. Results show that cement parameter, moisture content, water cement ratio,curing condition and other factors have influence on the strength and compressibility of dredged soil. Shear strength is gradually increasing with the increase of cement param-eters and decreases with the increase of moisture content. Under the same conditions, the minimum compressibility coefficient of cement soil is the best water cement ratio.
