Abstract：To study the coupling relationship between the resistivity of reinforced soil and the loading time,load magnitude,and strain of the reinforcement,a universal testing machine and mold are used to compress reinforced soil specimens.CPE3020 type steel-plastic composite reinforcement strips are embedded at designated positions,and a multimeter is used to measure the changes in resistivity of the soil specimens,investigating the resistivity response characteristics of small reinforced soil specimens.The experimental results indicate:The resistivity of the soil specimens decreases with the increase of loading time,load,and strain of the reinforcement;under the same degree of compaction,higher moisture capacity results in lower soil specimens resistivity;under the same moisture capacity,greater compaction leads to lower soil specimens resistivity;the smaller the degree of compaction,the earlier the sudden change in soil specimens resistivity occurs,and the weaker the bearing capacity of the specimen;the greater the degree of compaction,the later the sudden change in soil specimens resistivity occurs,and the stronger the bearing capacity of the specimen;when the reinforced soil specimens fails,the sudden change in resistivity has a good response characteristic for predicting the damage degree of the reinforced soil body.
