摘　　要：为研究固化剂在不同条件下对皮革污泥土电阻率特性的影响,分别在不同含水率、固化剂掺量和养护龄期下,分析了皮革污泥土电阻率的变化趋势,通过SEM微观形貌检测探究固化污染土电阻率变化的原因,研究固化污染土电阻率与无侧限抗压强度的关系。结果表明,随着固化剂掺量的质量分数(2.5%~10%)以及养护龄期(0 d~28 d)的增加,固化后的皮革污泥土电阻率增大了13.4%~49.8%。皮革污泥固化土的无侧限抗压强度与电阻率呈现近似幂函数关系。To study the effect of curing agents on the electrical resistivity characteristics of leather sludge soil under different conditions,the variation trend of leather sludge soil electrical resistivity was analyzed under different water contents,curing agent dosages and curing age,respectively,and the reasons for the change of electrical resistivity of the cured contaminated soil were further explored through SEM to investigate the relationship between the electrical resistivity of the cured contaminated soil and the unconfined compressive strength.The results show that the resistivity of cured leather sludge soil increases by 13.4%~49.8%with the further addition of curing agent dosage(2.5%~10%)and the rise in curing time(0 d~28 d).The relationship between the unconfined compressive strength and resistivity of the cured leather sludge soil shows an approximate power function.
