强震下返包胎面加筋挡土墙结构抗震性能模型试验研究
Experimental study of seismic performances of geogrid-wrapped tire-faced retaining soil walls under strong earthquakes
摘要
Abstract
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.关键词
