摘    要:利用水泥作为固化剂以提高软土地基的强度和减少软土地基的变形, 已经为沿海软土地区建设中较为普遍地采用。一般通过粉喷或深层搅拌法, 把水泥掺加拌和到软土地基中, 使它和软土中的物质组分发生物理化学反应, 以收到加固效应。通过对现场和室内的水泥土样品进行对比试验及宏观和微观的对比分析研究, 搞清了水泥土加固软土的作用机理, 提出了用水泥加固提高地基强度和节约水泥用量的建议。

关 键 词:加固效应  软土地基  水泥

Abstract:The portland cement as a consolidating agent for increasing the strength of Soft cohesive ground and decreasing its deformation, already is widespread used in construction in the coastal area. Usually using dry powder mixing methed or deep bed stirring method for mixing portland cement into soft cohesive ground and reacting physico-chemically, we can get reinforce effect.This research project is supported by Jiangsu Province Science and Technology Foundation (Grant No. 91246). A comparative test for the cement soil samples in laboratory and in-situ, and macroscopic and microscopic analizes made us to the mechanism of reinforcing the soft cohesive ground with portland cement. A proposal on increasing the strength of soft cohesive ground, and economizing portland cement is putted forward.
Keywords:Soft cohesive ground  Reinforce effect  Portland cement
