固化有机质土的抗剪强度试验研究
Experimental study on shear strength of stabilized organic soil
摘要
Abstract
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.关键词
