摘要:
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.
Abstract:
A new way of treating the waste clays into a useful fill material by adding quick lime is proposed in this paper. A series of laboratory tests were performed to investigate the behavior of dry density of the quick-lime-treated-dredged-clays. The effects of quick lime contents and initial water contents of dredged clays on dry density of quick-lime-treated soils are discussed. The relationship between dry density and water content is also analyzed and compared for both the air-dried original dredged clays and the quick-lime-treated soils. With introducing a new concept of increasing percent of dry density, the law on variation of dry density of quick-lime-treated soils is proposed. That is, the increasing percent of dry density has the same linear relationship with quick lime content for different initial water contents of dredged clays. In addition, this paper also suggests a simple method of predicting the dry density of treated soils, therefore the amount of test work can be greatly reduced.
