Experimental Study on Influencing Factors of Resistivity Characteristics of Fully Weathered Soft Rock Packing by LI Sha, YANG Lei, LIU Jie

“…In order to study the resistivity characteristics of fully weathered soft rock fillers,laboratory tests with different particle sizes and gradations are carried out to find out the influence of water content,particle size and coarse particle content on the resistivity characteristics of weathered soft rock fillers.The test results show that the larger the particle size and the more the content of coarse particles,the less conductive it is,and the conductivity of the weathered siltstone is slightly lower than that of the weathered argillaceous sandstone.In general,the resistivity decreases with the increase of water content,and the downward trend can be roughly divided into three stages,namely,the rapid decline,the slow decline and the gradual gradual and stable stage.The resistivity of fully weathered argillaceous sandstone filler is related to the content of coarse particles.When the water content is less than 14%,the content of coarse particles has a great influence on the resistivity.The correlation between the soil resistivity and water content is a power index function,and the relationship between the soil resistivity and dry density,water content and coarse particle content is preliminarily revealed,which provides a theoretical basis for the compaction quality detection of fully weathered clay soft rock filler.…”
