| Abstract | 地基处理化学固化法如水泥土搅拌法已经被广泛应用到实际工程中,研发绿色、低碳、环保的新型胶凝材料来部分或完全取代水泥,对于实现"碳中和·碳达峰"目标具有重要意义.本文通过一维固结压缩试验,探究了初始含水量、固化材料类型及其掺量、掺砂率以及养护时间等因素对生石灰激发粒化高炉矿渣(生石灰-CaO,粒化高炉矿渣-Ground granulated blastfurnace slag,GGBS)固化土和水泥(Portland cement,PC)固化土压缩特性的影响规律.研究发现,CaO-GGBS固化土与水泥土类似,具有明显的结构性,存在明显的结构屈服点和屈服应力,当竖向压力小于屈服应力时固化土的压缩性很小,而当压力超过屈服应力时其压缩性会突增,转变为高压缩性土体.CaO-GGBS固化土的屈服应力随着初始含水量的降低、固化材料掺量和养护龄期的增加而逐渐增大.CaO-GGBS对于高含水量软土的固化效果优于水泥. |
