提出了炉渣置换并注浆的软土地基处理工艺。变化配比制作置换软土地基的炉渣注浆试件,进行不同均质度条件下的力学性质试验,得到了炉渣注浆均质度变化与极限应变、极限强度、弹性模量、泊松比和残余强度等力学参数之间的关系。提高注浆均质度是保障炉渣置换软土地基整体刚度的有效途径,材料配比水∶水泥∶炉渣为1∶1∶4.7的注浆均质度为软土地基炉渣置换注浆工程应用的推荐值。 Proposed slag replacement and grouting soft soil foundation treatment process. The results show that the homogeneity of slag grouting changes with the ultimate strain, ultimate strength, elastic modulus, Poisson’s ratio And residual strength and other mechanical parameters of the relationship between. Improving grouting homogeneity is an effective way to ensure the overall stiffness of slag replacement soft soil foundation. The material matching ratio of water to cement: the grouting consistency of 1: 1: 4.7 for the slag is the replacement of grouting for soft soil foundation Recommended value.
