摘要: 非饱和土渗透系数的测量,是研究非饱和土渗透特性的重要方法,但由于渗透系数测量困难,多数研究仍然以理论为主。为试验研究非饱和土渗透系数,利用GDS系统,研究非饱和土渗透系数测量的试验方法,研究结果表明:基于GDS系统的非饱和土渗透试验细化了试验阶段,简化了试验过程,得到有效的试验数据,为试验研究非饱和土渗透系数提供了研究思路。、Abstract: The unsaturated soil permeability test is an important way to study permeability characteristics of unsaturated soil. Due to the difficulty of measuring permeability coefficient directly, most research work based mainly on theory. This paper study on the method for unsaturated soil permeability test. The results show that the unsaturated soil permeability test based on GDS system is efficient for measuring permeability coefficient which provide a good research approach.
