通过室内模拟试验,对比研究了生活污水污染前后水泥土抗压强度和电阻率的变化规律。试验结果表明,污染前后水泥土试块的无侧限抗压强度和电阻率均随着龄期的增加而增大,但是生活污水对水泥土强度和电阻率的影响随着时间的增加而逐渐加剧;水泥土试块的电阻率随无侧限抗压强度呈线性增长关系;建立了生活污水对水泥土强度影响的预测公式。
Pure water and household wastewater are used to manufacture cemented soil blocks to study the influence of the household wastewater on the mechanical properties of cemented soil by indoor simulation experiment. Variations of the unconfined compressive strength and the electrical resistivity have been investigated. The resuhs demonstrate that the peak unconfined compression strengths and electrical resistivity increase with the curing age; the electrical resistivity changes linearly with the unconfined compression strengths. The predicting formula about the influence of the household wastewater on the strengths of the cemented soil is established.
