| 摘 要： | 针对路基工程施工需要,对于两种不同钢渣掺量的钢渣稳定土在不同饱水时间以及不同失水-吸水干湿循环次数下的无侧限抗压强度和劈裂强度的变化规律进行了研究,并在最佳含水率附近探讨了钢渣稳定土对成型含水率的敏感性.试验结果表明,对于钢渣掺量为8%和15%的钢渣稳定土,在饱水试验和干湿循环试验中,钢渣稳定土的抗压强度和劈裂强度在初期急剧减小,最终均趋于稳定值,且随着钢渣掺量的增加,其水稳性得到改善.随着龄期的增长,成型含水率的变化对钢渣稳定土强度的影响逐渐减小,增加钢渣掺量也能够有效降低成型含水率变化对其强度的影响.

| Abstract: | In order to study the water stability of steel slag soil and direct the construction of road bed,the varying characters of unconfined compressive strength and splitting tensile strength in different soak periods and different wetting and drying cycles have been carried out in the state of optimal water content under certain compaction.The two strength indexes of steel slag soil were investigated with the different water content when sample formed.Test results showed that after different soak periods and dif... |
