中文摘要：

为探究养护龄期、硫酸钠含量、交流电频率等因素对水泥土电阻率的影响，首先用数字交流电桥测量水泥土试块的阻抗模并计算出电阻率，然后根据3因素3水平正交试验予以分析。结果表明：影响水泥土电阻率变化的主次因素依次是养护龄期、硫酸钠含量、交流电频率；水泥土电阻率随着养护龄期的增长而增加，随着硫酸钠含量和交流电频率的增加而减小。

英文摘要：

In order to study the influence of curing time, the content of sodium sulfate, and frequen- cy of alternating current （AC） on the electrical resistivity of cemented soil, the impedance modulus of a cemented soil block was measured and its electrical resistivity was calculated. The influencing factors were analyzed by the orthogonal method. The results show that the primary factor influencing the electrical resistivity of cemented soil is the curing time, the second is the content of sodium sul- fate and the third is the AC frequency. The electrical resistivity increases with the increase of curing time, and it decreases with the increase of the sodium sulfate content and the AC frequency.
