理化复合法改性淤泥的固结蠕变特性研究
Study on the Creep Characteristics of Slurries Modified by the Physicochemical Combination Method
摘要
Abstract
The physicochemical combination method is an effective approach for slurry treatment and resource utilization.To study the creep characteristics of slurries modified by this method,this paper conducted one-dimensional consolidation creep tests on modified slurry samples with varying initial water contents and different amounts of stabilizer.The long-term deformation characteristics of these samples were compared with those of slurries modified using the conventional cement solidification method.The results indicate that the creep deformation of the modified slurry samples decreases with decreasing load level,increasing curing agent content,and decreasing initial water content.With the increase of curing agent content and the decrease of initial water content,the change of void ratio of the slurries modified by physicochemical combination method decreased and the microstructure tended to be even.In addition,the creep deformation of the specimens modified by the traditional curing method is at least 3.11 times higher than that of the physicochamical method.Compared to the traditional curing method,the samples treated with the physicochemical combination method exhibit lower creep deformation and deformation rates,higher structural yield stress,and a more intact microstructure,highlighting the significant advantages of this method.关键词
