Experimental studies of coefficient of permeability of soil affected by water-soil interactions

In order to examine the influence of water-soil interactions on coefficient of permeability of soil,soil samples have been tested in laboratory with different chemical solutions,including deionized water,solution with different pH,and Na2SO4,NaHCO3,CaCl2,TP,TN solutions with different concentrations.The results indicate that the coefficient of permeability are changed,and there exist both positive and negative effects on the specimens in this test.The SEM photos show that dissolution and deposit...
