Abstract

The invention discloses a pullout and model dual-purpose test device for a reinforced earth structure of a tire as well as a test measurement method. According to the device, a reinforced earth model test can be performed through a top vertical loading system matched with a corresponding measurement system; and a large pullout test for reinforced materials such as the tire, a grill and the like can be performed through the vertical loading system combined with a side surface pullout load applying system and a displacement measurement system. The device comprises a loading system, a model system and the measurement system. According to the device and the method, corresponding loading and measurement systems of the pullout test and the model test are combined, and compared with the conventional model and pullout test device, the test cost is reduced; the device overcomes the defect that the conventional pullout device cannot perform a pullout test for a dimensional reinforced material such as the tire and the like; the measurement system has comprehensive monitoring content, can perform precise measurement on force, displacement and the like of a reinforcement material and filled earth, and a stress-strain status is reflected truly; and the device and the method can be applied to the model test and the pullout test for an unconventional reinforced earth structure such as the tire and the like.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering model tests, in particular to a tire-reinforced soil structure pull-out model dual-purpose test device and a test measurement method. [0002] Background technique [0003] The waste tire reinforced soil structure has good earthquake resistance, excellent durability, simple construction, low cost, economical and environmental protection, and has broad application prospects in engineering practice. In the tire-reinforced soil structure, factors such as the deformation characteristics of the reinforced material, the tensile resistance of the tire string, and the pull-out resistance will affect the stability and deformation characteristics of the reinforced soil structure, and the tensile performance of the interface between the reinforced soil and the reinforced soil. It is the key to discuss the working behavior, failure mode and reinforcement mechanism of reinforced soil, and it is the pre...
