| Abstract: | In this paper , the subgrade soil defects of shuohuang railway is taken as an example .By using Van der Pauw method , the changing regulation of soil resistivity with the soil salt and water content variation is analyzed through the moisture gage developed by us and the testing system is verified .The experimental results indicate that the testing system has favorable stability and repetition within the permission scope .With the ad-vantages of simple operation , fast response and high sensitivity , this method can be widely applied on construc-tion site for moisture content determination . |
