摘要
为了研究荷载对粘性土渗透系数的影响,研制了荷载作用下粘性土渗透系数量测的新型室内试验装置——变水头压力渗透仪,该装置同时具备土样制备、渗透系数测量及位移量测等功能.利用该装置对不同初始压实度粘性土进行了相关试验,测定出不同荷载条件下土体的渗透系数值.通过Origin 8.0软件进行回归分析后,得到荷载与渗透系数的对应关系.
To study the influence of load on the permeability coefficient of clay,the water permeability measurement apparatus with varying head and compressive stress is developed,which has the functions of soil preparation,water permeability measurement,displacement measurement.Using this apparatus on the clay with different initial compaction,the water permeability under different load is measured,the corresponding relationship of load and water permeability is obtained by Origin 8.0.
