土体固结粉在软土地基加固中的应用研究

摘要

针对上海地区软土地基特点,利用工业废渣为主要原料配制成新型土体固结材料——土体固结粉.通过室内的无侧限抗压强度及XRD试验得出其固化土的强度性能及加固机理;再通过室外原位搅拌桩施工及芯样试验进行分析,研究了土体固结粉在软土地基加固实际工程中的适用性.%According to the characteristics of soft soil foundation in Shanghai , a new soil consolidation material -soil consolidation powder was prepared by using industrial waste residue as the main raw material .Through unconfined com-pressive strength and XRD test ,the strength and properties of the cured soils were obtained .The applicability of soil con-solidation powder in the actual engineering of soft soil foundation was analyzed by outdoor in-situ mixing pile construction and core sample test .
