摘要
石灰土是一种在土建工程中得到广泛应用的建筑材料。石灰具有改善土质性能的作用,针对具体的土质及灰质,通过大量室内试验,探讨不同灰土比、密实度、含水率等因素对石灰土直剪强度的影响;同时,试验分析了养护石灰土的工程特性,特别是探讨了养护龄期及冻融循环对石灰土无侧限抗压强度的影响。通过试验研究,进一步了解了石灰土的特有工程性能,从而可为工程设计提供可靠的参考依据。
The lime soil is a kind of building materials used widely in engineering and the lime can improve the properties of soil. The influences of different lime-soil ratio, density and moisture content on the shear strength of lime soil are studied and the engineering properties of the maintained lime soil are analyzed. The influences of the maintained time and the freeze-thaw cycling on the unconfined compression strength of lime soil are discussed. Through the experimental study, the special engineering features of lime soil are realized.
