摘　　要：目的研究不同因素对橡胶水泥土的电阻率的影响.方法利用二相电极法在室内测试橡胶水泥土的电阻率.结果随着水泥掺量的增加,橡胶水泥土的电阻率呈递增趋势;随着橡胶粉掺量的增加,橡胶水泥土的电阻率呈递减趋势.大粒径橡胶粉对橡胶水泥土电阻率的影响大于小粒径橡胶粉.结论橡胶水泥土电阻率与橡胶水泥土无侧限抗压强度在适当的水泥掺量和橡胶掺量的情况下存在很好的相关性.可以通过对橡胶水泥土电阻率的测定来推算橡胶水泥土无侧限抗压强度的变化规律.Based on the test of measuring resistivity of rubberized cement-soil with the method of two-phase electrode,influence factors on reslstivity are studied. Resistivity will increase as the cement content increases and decrease as the rubber powder content increases. Rubber powder with bigger particle size would affect resistivity greater than the smaller ones. The results show that there is a correlation between resistivity and compressive strength of the rubberized cement-soil under the condition of proper cement and rubber powder content. So variation of rubberized cement-soil compressive strength can be predicted by measuring the resistivity.
