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 for the waste rubber tire hoop bulk material was proposed. The elastic modulus of discarded rubber tire was obtained by carrying out tensile test of rubber tire strip. Using waste rubber tires-sand composite axial compression test, the rules were discussed including the influence law of loading system and lateral conditions on foundation bearing capacity, stress distribution of inner wall of tire and variation law of soil stress inside laminated body. The results show that compared with fast and slow loading system, the sedimentation of the superposition is the smallest when loading and unloading in one direction, the self-recovery ability and bearing capacity are optimal. The bearing capacity of the composite is better under confined conditions, 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 law of the inner wall of the tire is very different. In the same radial plane, the closer to the center of the superposition, the smaller the effect of rubber tire ring, and the larger the soil stress. The research results can provide theoretical guidance for the practical application of the waste rubber tire-sand composite composite foundation .
