Experimental study of factors affecting strength of reinforced soil

FU Hua,LIN Hua,CAI Zheng-yin(Nanjing Hydraulic Research Institute,Nanjing 210029,China)  
Researches on factors affecting strength of reinforced soil are performed by using lab triaxial tests.The change law of strength of samples with different reinforced conditions is discussed,and the corresponding factors are tested.The results show that the effect of the reinforced action becomes obviously while the axial strain increases;for the samples with low strength,the strength increases greatly after being reinforced;for the same samples,the higher the strength of reinforced material is,the more obvious the reinforced effect is;for the same reinforced material,the more the reinforced layers are,the smaller the layer spacing is,the more obvious the reinforced effect is;the higher the density of the sample,the more obvious the reinforced effect is.
