为了将废弃的高含水量疏浚淤泥处理成松散可压实土,为高含水量疏浚淤泥的有效利用开辟新的途径,尝试添加生石灰处理高含水量疏浚淤泥.通过大量的室内试验,研究了高含水量疏浚淤泥生石灰处理土的击实性状,探讨了原泥初始含水量和生石灰掺入比对干密度的影响,分析比较了风干后原泥和生石灰处理土的干密度与含水量的关系.研究结果表明:通过导入干密度增长率的概念可以将处理土的干密度、原泥初始含水量及生石灰掺入比的关系进行归一化,干密度增长率与掺灰比具有很好的线性变化规律.依据干密度的变化规律,提出了干密度的经验预测方法,利用此预测方法,可以大幅度减少试验的工作量,有利于在实际工程中的推广应用.
In order to dispose of waste high-water-content dredged silt into loose compacted soils, a new way for effective utilization of high-water content dredged silt is to be explored, and quick lime is used to treat high-water content dredged silt.A large number of indoor experiments were conducted to study the effects of high The effect of initial moisture content and quick lime incorporation ratio on the dry density of dredged silt treated by quicklime with water content was discussed. The relationship between dry density and water content of raw and quicklime treated air was analyzed and compared. The results show that the concept of dry density growth rate can be used to normalize the relationship between the dry density of treated soil, original water content of raw mud and the ratio of quicklime. The dry density growth rate and ash content ratio have good linearity According to the rule of variation of dry density, an empirical prediction method of dry density is put forward. By using this prediction method, the workload of experiment can be greatly reduced, which is beneficial to popularization and application in practical engineering.
