## 3 Results and Analysis  
### Compressibility of Line-Stabilized Slurry  
The log(1 + _e_)-log \(p\) curve for the lime-stabilized slurry is shown in Figure 2 below [26]. The \(p\) is the applied vertical effective stress and the \(e\) is the void ratio. The compression curve of the remolded slurry was a straight line, while the compression curve of the lime-stabilized slurry was represented by two straight lines with different inclines. The horizontal coordinate of the intersection of the two lines marked the remolded yield stress of the soil sample [27]. Figure 3 below shows the compression indices of each group of lime-stabilized slurry at different dosage levels, where C\({}_{\text{S1}}\) and C\({}_{\text{S2}}\) are the compression indices of the stabilized slurry before and after yielding, respectively. The test results showed that increasing the lime dosage causes the C\({}_{\text{S1}}\) of the stabilized slurry to decrease and the C\({}_{\text{S2}}\) to increase. Taking the Wenzhou slurry as an example, the C\({}_{\text{S1}}\) of the stabilized slurry at a 1% lime dosage was only 32.3% of that of the remolded slurry, and C\({}_{\text{S1}}\) was found to decrease gradually with the increase in lime dosage. When the vertical effective stress exceeded its remolded yield stress, the compression index of the stabilized slurry was higher than that of the remolded slurry, and the compression index increased gradually with the increase in lime dosage.  
Meanwhile, the granular gradation was observed to significantly affect the compression index of the lime-stabilized slurry. With the increase in clay content, the C\({}_{\text{S1}}\) and C\({}_{\text{S2}}\) of the stabilized slurry were noticed to gradually reduce. Consequently, the effect of lime stabilization on the slurry with high clay content was more significant than that on the slurry with high silt content.  
As shown in Figure 4, the presence of significant remoldeded yield stress in the-line-stabilized slurry was interpreted to indicate that lime stabilization could enhance the structural properties of the slurry with high water content. Meanwhile, the remolded yield stress of stabilized slurry was observed to increase with the increase in lime dosage, and the compressibility of stabilized slurry with a 3% lime dosage was shown to be the lowest.  
When comparing the remolded yield stress values of the slurry with different gradations, the effect of granular gradation on yield stress is similar to the compression index. Taking the Hangzhou slurry and Zhoushan slurry as examples, the remolded yield stress of the Hangzhou slurry was substantially greater than that of the Zhoushan slurry with a 1% lime dosage. With the further increase in lime dosage to 2% and 3%, whereas the remolded yield stress of the Hangzhou slurry did not change significantly, that of the Zhoushan slurry still maintained an increasing trend. Therefore, the clay content directly influenced the remolded yield stress value of stabilized slurry, and the Hangzhou slurry formed a stable structure with a 2% lime dosage; thus, the further increase in lime dosage did not significantly reduce its compressibility. Therefore, more significant changes were noted in the compressibility of the slurry with high clay content than that of the slurry with high silt content after lime stabilization.
