摘要:
利用长安大学改装的K0固结仪,对原状土样与重塑土样进行了固结渗透试验,根据试验所得到的数据,分别对2种土体的变形与渗透特性进行了分析,并结合太沙基一维固结理论,得到了固结系数的确定方法; 在此基础上,对固结系数的变化进行了非线性分析,揭示了固结系数在固结过程中的变化规律及土体结构性对它的影响,这对准确计算地基土体的固结沉降有指导作用。
Abstract:
Experiments of consolidation and permeability on undisturbed soil and remolded soil were performed respectively by using K0 consolidation instrument modified by Chang'an University. The deformation and permeability property were analyzed according to the data got from the experiments, and the determined method of one-dimensional consolidation coefficient was gained by using Terzaghi's one-dimensional consolidation theory. Based on this, the consolidation coefficient was analyzed by this method in order to reveal its changing law and influence from soil structure during consolidation. This has guiding effect for accurately calculating soil ground consolidation settlement.
