摘　　要：掺和废弃钢炉渣的混合土是一种新混合填土路基材料,在常规不固结不排水三轴压缩试验基础上研究了混合轻质黏土的强度特性,分析了钢炉渣掺入比以及龄期分别对应力应变特性、破坏形式及抗剪强度的影响规律,得出了应力应变特性、破坏形式及抗剪强度随钢炉渣掺入比以及龄期变化的规律是基本一致的,钢炉渣掺入比越大,混合水泥土的早期强度越低,但随着龄期的增长,后期强度增长越明显,研究得出的混合水泥土理想的钢炉渣施工掺入比在能源节约、环境保护方面可以有一定的应用前景。Mixed light-weight soil blended waste slag is a new hybrid material in conventional unconsolidated and undrained triaxial test on the basis of the strength characteristics, slag incorporation ratio and age correspond to stress-strain properties, failure form and shear strength of the law, and the conclusions are achieved that the stress-strain behavior, failure modes and shear strength incorporation ratio and age changes in the law are consistent with the slag, with the high slag incorporation ratio, the intensity of mixed soil has lower strength, but with the age of the growth, the growth of the late strength is more obvious, so the mixed soil in energy conservation, environmental protection, and overcoming the creep damage will have a lot of applications.
