프리캐스트 콘크리트 포장에 프리스트레싱 기법 도입을 위한 검토
Application of Prestressing Technology for Precast Concrete Pavements
- 발행 : 2008.04.24
초록
The important factors that should be considered when designing and constructing the precast prestressed concrete pavement were investigated in this study. Those factors included traffic and environmental loads, interaction between the concrete slab and the underlying layers, determination of the slab thickness and the prestressing amount. In addition, the behaviors of the precast prestressed concrete pavement when post-tensioning was applied were analyzed using a finite element model. The effects of the number of anchors, the horizontal resistance of underlying layers, the pavement length, the slab thickness, and the bearing area of the anchorage on the distribution of compressive stresses were analyzed.
