Experimental Research On Electrical Resistivity Character Of Multi-phase Mixture Of Soil-stone

Based on the domestic and foreign experts and scholars on earth and stone resistivity of the study, multiphase debris through the medium of resistivity of experiments, and theoretical analysis, test data analysis, by the multi-phase debris composite media with the earth-rock than the rate of resistance, moisture content, The relationship between the number of compaction, summed up than on the earth-rock, water, is the number-three variables multiphase debris composite media resistivity model.The main research work are as follows:1,adopted in Chongqing common-weathered mudstone weathered, broken after the formation of soil, limestone stone, earth-rock and water production complex multi-phase medium samples, soil measurement of raw materials, natural stone state of physical indicators, and water resistance rate.2,a light-compaction, multimeter, a self-made copper round indoor multi-phase debris composite media resistivity test. Multiphase medium earth-rock samples of the compaction forming (cylindrical), equivalent to sample-diameter cylinder diameter is 10.2 mm. Forming soil samples, from top to bottom in two Nianshang copper surface, after the copper wire used to access, use multimeter measured resistance, the resistance rate of soil samples as follows:. A multi-phase testing of earth-rock in the earth-rock than the media were 5:5,6:4,7:3,8:2, the moisture content of 5%, 10%, 15%, 20%, respectively, the number of compaction 8,16,24,32 times the rate under the conditions of the resistance.3,based on 1942, Archie passed the test on the soil resistivity with the structure of the relationship between the non-applicable to the saturation of the clay model of resistance and pure rock and Archie model, the establishment of a multi-phase debris composite media resistivity model .4,through statistical analysis of data from tests to verify the multi-phase debris composite media resistivity model of rationality, established a multi-phase composite media resistivity of earth-rock parameters of the model range, and various parameters and earth-rock ratio, moisture content, Compaction of the relationship between the number.
