چکیده مقاله
In this research, optimization of shredded tire content in sand for increasing its shear strength parameters and also its effects on force displacement curve has been investigated These parameters have been studied using direct shear tests Sand and tire shred sand mixtures by volume percentage of 20, 25, 30, 35 and 40 percent , using two sizes for tire particles has been examined and optimized percentage of shredded tire has been found to be 30 percent by volume Shear strength of samples consisting 1 5 to 3 mm tire shreds were increased up to 26 1% A physical model of a soil slope has been studied with pure sand and shredded tire sand mixture in two series of tests, one with strip footing located in 0 5B B is foundations width and second one 1 15B from slope's edge The results show that adding shredded tire results in 35% increase in bearing capacity for foundation placed 0 5B from slope’s edge and 39% increase for samples with 1 15B loading from slope's edge In last section of this study materials movement patterns after failure in physical model were studied and the results showed that adding shredded tire to sand, makes moving materials volume less than slopes with pure sand material
