摘要
长寿命沥青路面是国际道路工程界提出的新技术。本文运用三维有限元程序对4种路面结构进行对比应力分析,分析了结构组合变化对层底弯拉应变的影响。为设计长寿命路面结构提供了必要的理论基础。
The perpetual pavement was an advanced technology represented in engineering field. The stress states of four pavement structures were calculated by three-dimension finite element method to analyze the influence of different structural combinations on the tensile strain at the bottom. This is also developed as the theoretical foundation for the design of perpetual pavements.
