【摘要】 针对路基工程施工需要,对于石灰钢渣稳定土在不同饱水时间以及不同干湿循环次数下无侧限抗压强度和劈裂抗拉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的强度对成型含水率的敏感性.结果表明:在饱水试验和干湿循环试验中,石灰钢渣稳定土的无侧限抗压强度和劈裂抗拉强度在初期急剧减小,但最终均趋于稳定;随着龄期的增长,成型含水率的变化对石灰钢渣稳定土强度的影响逐渐减小,增加钢渣掺量能够有效改善石灰钢渣稳定土的水稳性能.更多还原

【Abstract】 In order to study the water stability of lime steel slag stabilized soil and direct the construction of road bed,the varying characters of unconfined compressive strength and splitting tensile strength in different soaking 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 lime steel slag stabilized soil were investigated with the different water content when sample formed.Test results showed that after different soaking periods and different wetting and drying cycles,both the unconfined compressive strength and the splitting tensile strength of lime steel slag stabilized soil decreased sharply at the initial stage,and drove to stability of status at last.For different water content,the influence on both the unconfined compressive strength and the splitting tensile strength of lime steel slag stabilized soil was decreased by increasing the curing period of sample.As more steel slag added,the lime steel slag stabilized soil had better water stability.更多还原
