摘要

摘要: 材料的击实性能和抗压强度是进行地基处理选取材料时考虑的两个重要性能指标,可以作为地基处理施工的质量控制参数,对工程性质有重要影响。石灰和炉渣均为轻质材料,合理使用石灰炉渣混合材料进行地基处理可以显著减小地基的附加应力,同时可大量利用工业废料,是一种经济环保的方法。从理论上分析了石灰炉渣混合材料强度提高的机理,并对石灰炉渣混合料的性质进行了试验研究,通过对不同配比的混合材料进行击实试验、无侧限抗压强度试验,得到了不同比例混合材料的击实性能和无侧限抗压强度。结合一则工程实例,对石灰炉渣轻质材料桩法处理地基进行分析计算,表明该材料可以应用于地基处理。

Abstract: The compaction performance and compressive strength of materials are important indices need to be considered when selected in foundation treatment. The two factors can be used as quality control parameters in construction and have important they are influence on engineering properties. Lime and slag are both lightweight materials. The rational use of lime-slag mixed materials in foundation treatment can achieve the results of reducing the additional stress in foundation, and it is an economic and environmentally friendly way because vast industrial waste can be used. The strength increasing mechanism of lime-slag mixed materials is theoretically analyzed. Compaction tests and unconfined compressive strength tests are on the lime-slag mixed materials with different mix proportions by volume are carried out. The compaction property and unconfined compressive strength are obtained. Combined with an engineering example, a foundation treatment project using piles of lime-slag mixed lightweight materials is analyzed and calculated, indicating that this kind of mixed materials can be used in foundation treatment.
