分别以固化土7d的粘聚力和内摩擦角作为评价指标,通过开展固化有机质土的正交快剪试验,研究复合固化剂的固化效果,结果发现固化土的粘聚力和内摩擦角均得到了较大幅度的提高,且粘聚力提高更为显著。对于粘聚力:水泥影响最为显著,高效减水剂FDN影响次之,玻璃纤维更次之,水玻璃影响最小;而对于内摩擦角:水泥影响最为显著,玻璃纤维影响次之,高效减水剂FDN更次之,水玻璃影响最小。
The cohesion and internal friction angle of solidified soil 7d were taken as evaluation indexes respectively. Through the orthogonal rapid shear test of solidified soil, the curing effect of compound solidified agent was studied. It was found that both cohesion and internal friction angle Has been more substantial increase, and cohesion increased more significantly. For the cohesion: the cement has the most significant effect, followed by the FDN of the high-efficiency water reducer, followed by the glass fiber and the water glass with the least impact. For the internal friction angle, the cement has the most significant effect, followed by the glass fiber, FDN is the second, water glass minimal impact.
