Numerical Study of Geosynthetic-Aggregate Interaction Under Wheel Loading
| 项目名称： | Numerical Study of Geosynthetic-Aggregate Interaction Under Wheel Loading |
| 摘要： | Interaction between geosynthetics (geogrid or geotextile) and aggregates under traffic wheel loading has been considered as one of high-priority problems by the Transportation Research Board. The practical use of geosynthetics above the subgrade or in base course has demonstrated their effects on the reduction of rut depths and the prolonging of pavement life. Continuum mechanics treats aggregates as a continuum media, which cannot properly simulate the movement and interaction of aggregates with geosynthetics. The proposed research will investigate this interaction using a numerical software - particle flow code (PFC), which is based on micromechanics. Micromechanics assume that aggregates are a granular assembly, in which stresses are transmitted by contacts between grains, each of which has a different direction. The numerical study will investigate the mechanisms involved in the interaction between geosynthetics and aggregate and provide guidance for the selection of geosynthetics and aggregates and the design of geosynthetic-reinforced base course under traffic wheel loading. |
