吹填土固结速度影响因素的分析
首发时间:2008-09-19
摘要:对吹填土固结的三个过程---主固结、次固结和干燥,从微观结构探讨了固结速度的影响因素。主固结的速度影响因素有:双电层厚度,吹填土的渗透特性,电位势,土水势,粒间作用力。次固结的速度影响因素有塑性指数,粘粒含量,矿物成分,含水量,灵敏性,温度,比表面积,结合水膜厚度。干燥的速度影响因素有含水量,渗透性,气温、降水量、温度、昼夜温差,风速等

Study on consolidation velocity factors of dredged fill
Abstract:Influencing factors of consolidation velocity were investigated from microstructure in this paper, on three consolidation processes of dredged fill: primary consolidation, secondary compression, and desiccation. Influencing factors of primary consolidation velocity were as followes: the thickness of electronic double layer;, permeability characteristics, electric potential, soil water potential, interparticle force; Influencing factors of secondary consolidation velocity were as followes: plasticity index, clay content, mineral composition, water content, sensitivity, temperature, specific surface, the thickness of water film; Influencing factors of desiccation velocity were as followes: water content, permeability characteristics, air temperature, rainfall, temperature, day and night temperature, wind velocity and so on.
