中文摘要：

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。

英文摘要：

The cohesion and internal friction angle of stabilized soil in 7 days were used as the evaluation index of stabilization.The influence of factors of solidifying agent on the stabilization of artificial organic soil was studied by orthogonal test of shear strength.It is found that both cohesion and internal friction angle of stabilized soil are significantly improved,and the stabilized effect of cohesion is better than that of internal friction angle.The stabilized effect of cohesion is concerned,the cement is the most important and the water-reducer FDN and the glass fiber take the second and the third place,respectively.The influence of water glass is the least.However,to the stabilized effect of internal friction angle,the cement is the most important and the glass fiber and the water-reducer FDN take the second and the third place,respectively.The influence of water glass is the least.
