| 摘 要： | 在疏浚土的化学加固研究中，化学剂的加入会直接影响疏浚土的沉降过程。以不同剂量、含水量、疏浚土组成为影响因素，观测并推算了各组试样的沉降过程中泥面高度、沉降速率、孔隙比、含水量、湿密度等参数随时间的变化情况，试验研究结果表明:化学剂在沉降速率和沉降稳定时间方面有很大的提高；化学剂的作用效果，随粘粒含量增加而降低。

| Abstract: | In the study of dredged soil being reinforced by chemical process, adding chemical agent will affect the settlement of the soil directly. As agent consumption, water content and composition of dredged soil are the affecting factors, how the parameters of each group of sample, including mud surface height, settlement velocity, void ratio, water content, wet density, change with the time was observed and calculated. The study result shows that chemical agent could improve the settlement velocity and stabilization time but its effect will decrease with increase of clay content. |
