玄武岩纤维贫混凝土复合式沥青路面荷载应力分析

Analysis of Load Stress for Basalt Fiber Reinforced Lean Concrete Composite Asphalt Pavement

在三维等参元理论和弹性层状体系理论的基础上,运用大型通用有限元分析软件ANSYS,分析了玄武岩纤维贫混凝土基层沥青复合式路面(BFRLC+AC)荷载应力,确定了路面结构的临界荷位,及BFRLC板的合理板长,研究了不同沥青面层厚度、沥青面层模量、BFRLC板厚度、BFRLC板模量及基础模量对玄武岩纤维贫混凝土基层层底应力的影响。为BFRLC+AC复合式路面结构设计提供一定的理论基础。

Based on the theory of three- dimensional isoparametric element and elastic layered system theory, using the large general finite element analysis software ANSYS, this article analyzed the load stress of the basalt fiber lean concrete base with asphalt pavement composite （ BFRLC ＋ AC）, deter- mined the critical load of pavement structure, and the reasonable length of BFRLC plate, studied the in- fluence of basalt fiber reinforced lean concrete base layer bottom stress by the different asphalt layer thickness,modulus of asphalt road surface, BFRLC plate thickness, BFRLC plate modulus and founda- tion modulus. To provide certain theoretical basis for BFRLC ＋ AC compound pavement structure design.
