以标准砂及普通硅酸盐水泥为试验材料，制作水泥固化锌污染土样，进行了一系列电阻率和无侧限抗压强度试验。研究了交流电频率对水泥固化锌污染土电阻率的影响、不同含量锌离子对水泥缓凝作用的影响、锌离子含量和龄期分别对水泥土电阻率和强度的影响、电阻率与无侧限抗压强度的关系。结果表明：电阻率随电流频率的增加而明显降低，尤其当频率低于50 kHz时为甚；不同含量的锌离子对水泥土的缓凝作用影响明显，随着锌离子含量的增大，水泥土强度的充分发挥所需时间逐渐增长，但在锌离子含量为500 mg/kg时，缓凝作用表现异常；电阻率和强度均随龄期的增加而增长，随锌离子的含量的增加上下波动，电阻率在锌离子含量为50 mg/kg和500 mg/kg时出现极值，强度在锌离子含量为100 mg/kg和500 mg/kg时出现极值；在各个龄期下，电阻率与强度均呈现出很好的线性关系。

The standard sand and ordinary Portland cement were selected as the experimental materials to prepare the samples of zinc contaminated soil solidified by cement. A series of tests was conducted to determine the unconfined compressive strength and electrical resistivity of the prepared samples. From these experiments, the effect of the current frequency on the electrical resistivity is investigated, and the influence of zinc ion concentration and curing time is also discussed on the delayed coagulation of cement, the electrical resistivity, unconfined compressive strength, the electrical resistivity and unconfined compressive strength. The results show that the electrical resistivity decreases significantly with the increase of current frequency, especially when current frequency is lower than 50 kHz. With the delayed coagulation influence of zinc ion content on cemented soil, the strength always grows slowly with the increase of zinc ion content but when the zinc ion content is up to 500 mg/kg, the delayed coagulation is abnormal. Both the electrical resistivity and strength increase with the increase of curing time, and fluctuate with the increase of zinc ion content. The electrical resistivity reaches a minimum and a maximum respectively at the zinc ion contents of 50 mg/kg and 500 mg/kg, and strength reaches a minimum and a maximum respectively at the zinc ion content of 100 mg/kg and 500 mg/kg. There exists a good linear relationship between electrical resistivity and unconfined compressive strength in different curing times.
