摘　　要：水泥土的强度主要源于水泥与土体之间的水化反应产物的凝硬反应。水泥土的水泥含量直接决定了水泥土的强度,表示水泥含量的参量很多,其中水灰比是表示水泥土强度的最有效参量。水灰比与水泥土的无侧限抗压强度和前期固结压力之间有很好的相关关系。Improvement of the properties of cement-stabilized soil is attributed to the soil cement reaction, which produces cementitious materials in the soil-cement matrix. The soil-cement reaction provides a clear basis to explain the improvement in strength of stabilized soil. The strength of stabilized soil depends on the cement content. The strength development of stabilized soil is solely dependent on the water-to-cement ratio, and the water-to-cement ratio is taken as an effective parameters to express strength. There are predictable correlations between the water-to-cement ratio and unconfined compressive strength and preconsolidated pressure of cement-stabilized soil .
