聚丙烯纤维加筋红黏土抗剪强度特性试验研究
Experimental study on shear strength of polypropylene fiber reinforced red clay
摘要
Abstract
To study the effect of blending polypropylene fiber on the red clay, a series of samples were prepared and subjected to the triaxial compression test. The results indicate that mixing with a certain amount of fiber can significantly increase the shear strength of red clay. Fiber can improve cohesion of the red clay, but it has little influence on friction angle. The cohesion of polypropylene fiber reinforced red clay is obvious higher than that without fiber, and the rate of enhancement is between15% to108%. However friction angle basically fluctuations near that of the red clay. When content of fiber is 2‰, the shear strength and cohesive both get maximum. It is reasonable to believe that "the optimum fiber content" is 2‰. The research results of this paper can provide reference for reinforced soil embankment.关键词
