摘要：The use of cement is a common technique to improve the bearing capacity of muddy coast foundation, and the determination of compression parameter of cemented soft clay is of great importance in the design process of solidification engineering. One-dimensional consolidometer was used to measure the vertical compression of cemented clay at different cement content and curing time. Test results indicate that cemented clay formed under seawater condition is a kind of strongly-structured soil with a relatively low compressibility. Yield stress increases with cement content and curing time, while compressibility decreases with the increase of cement content and curing time. The compress deformation is rather small with less vertical load, but significant compress deformation occurs when vertical load is greater than yield stress. Statistical data show that the yield stress can be used to represent the effect of cement content and curing time on compressibility of cemented clay. And a power function relationship exists between compressibility and the yield stress within the range considered in this study.
