Sun J., Chu Z., Luo W., Wang M., 2015, Experimental Study on Application of Used Tires in Rock Shed Cushion Layer, Chemical Engineering Transactions, 46, 661-666.
The used tires cushion layer for rock sheds can take advantage of tires radial stiffness and deformation ability, cushioning rockfall impact to protect the rock sheds roof. Quasi-static compression and pseudo-static test results show that: Bare used tires with small radial stiffness and good radial elasticity cannot dissipate rockfall impact energy. Bare used tires can be used as cushioning material. Winded with steel wire and filling sand bag can increase the tires radial stiffness and improve its bearing capacity. The effect of filling sand bag is better than winding wire under the same condition, and will also be more economical. Winding wire and filled with sand bag can make used tire perform significant non-linearity character under radial stress, so it has an improved energy dissipation capacity. Tires can absorb energy after winded with wire and filled with sand bag and tires filled with sand bag will perform better in absorbing impact energy than that of winded with wire. Better energy absorption characteristics of tires filled with soaking sand bag is found in pseudo-static test.
