Abstract:In order to explore a new method of foundation reinforcement and solve the environmental problems caused by waste rubber tire stacking, a new type of foundation with the waste rubber tire hooping granular material was proposed. The elastic modulus of discarded rubber tire was obtained by carrying out tensile testing on rubber tire strip. By using axial compression test on waste rubber tires-sand composite, the rules were discussed, including the influence of loading system and lateral conditions on the foundation bearing capacity, stress distribution of inner wall of tire, and soil stress inside the laminated body. The results show that, compared with fast and slow loading system, the sedimentation of the superposition is the smallest, and the self-recovery ability and bearing capacity are optimal when loading and unloading in one direction. The bearing capacity of the composite is higher when under confined condition, but the self-recovery ability of the composite is not affected by confined condition. Under the condition of no or no limitation, The stress distribution around the inner wall of the tire is quite different. In the same radial plane, the closer to the center of the superposition, the smaller the effect of rubber tire ring, and the greater the soil stress.
