To enhance the adoption and application of modular waste tire-faced retaining walls in earthquake-prone areas
we introduce the concept of geogrid-wrapped tire-faced retaining walls. A shake table test model was designed for this wall
considering the dynamic similarity ratio between soil and structure. Several factors were considered
such as geogrid wrap types
tire binding modes
foundation depth
and reinforcement length
to assess the wall’s seismic performance under strong earthquakes. The dynamic response characteristics
including wall acceleration
lateral displacement
and dynamic earth pressure on the wall back
were analyzed and compared to those of geogrid-stripped reinforced tire-faced retaining walls and traditional retaining walls. Key factors influencing the seismic performance of geogrid-wrapped walls were identified
revealing that the non-folded and full-bound mode provides superior seismic performance. It was found that
compared to foundation depth
reinforcement length more significantly enhances the seismic performance of the wall. A correlation between geogrid dynamic strain and local wall deformation was established
providing a reference value for wall design based on lateral displacement.
