摘要
采用基于非饱和瞬态流理论的TRIM系统,量测了改性淤泥固化土的土—水特征曲线(SWCC),分析了压实度、养护龄期和水泥掺量等因素对其SWCC的影响,并根据改性淤泥固化土SWCC的试验结果,分析了与初始孔隙比相关的SWCC模型参数预估模型,进而建立了考虑压实度和水泥掺量影响的改性淤泥固化土SWCC模型,通过分析不同影响因素下的SWCC,验证了所提出SWCC模型的合理性。
The Soil-Water Characteristic Curve（ SWCC） of solidified sludge soil modified with cement was measured by TRIM system based on unsaturated transient flow theory. The influence of compaction degree,curing age and cement content on SWCC was emphatically analyzed. According to the experimental results of SWCC on cement-modified sludge soils,the established method for predicting the parameters of SWCC model related to the initial void ratio are analyzed,and then the SWCC model considering the effect of compaction degree,curing age and cement content is established. The SWCC model is proved to be reasonable by evaluation the effect of different influencing factors.
