清淤淤泥的固结特性试验研究
Experiment on consolidation properties of dredged material
摘要
Abstract
Dredged material generated in sediment cleaning engineering of Tai Lake is usually placed in the storage yard and improved by drainage consolidation method before using in the projects. It is necessary to learn the consolidation properties of dredged material to predict settlement and consolidation rate. After improving the consolidometer, three kinds of dredged material with different initial water contents and one kind of remodeling soft soil were tested under low consolidation pressure to study consolidation properties. Test result shows that compression process of dredged material under low pressure can be described linearly by e -lgp curve, compression index of dredged material is affected markedly by initial water content. Coefficient of consolidation ascends in small range with the increase of consolidation pressure (about 10-4cm2/s) and coefficient of permeability is quite low (about 10-7 cm/s).关键词
