| 摘 要： | 通过大量的室内试验，研究了高含水率疏浚淤泥添加生石灰拌和而成的松散土的含水率变化规律。导入含水率降低率的概念，得出处理土含水率降低率随掺灰比的变化与原泥初始含水率无关，含水率降低率随着掺灰比的增加而线性增加的变化规律。根据得出的含水率变化规律，提出了处理土含水率的简单实用的预测方法。利用已有文献的试验数据验证了所提出的处理土含水率的变化规律和预测方法的有效性。

| Abstract: | A series of laboratory tests are performed to investigate the change of water content for quick lime treated dredged clayey soils with different quick lime contents and original water contents of dredged clays. With introducing a new concept of decreasing ratio of water content, the change law of water content of treated soils is obtained. That is, the decreasing ratio of water content has the same linear relationship with quick lime content for different original water contents of dredged soils. In addition, a simple method for predicting the water content of treated soils is proposed; and its effectiveness is verified with the data published in literatures. |
