摘　　要：通过对连续配筋路面的分析,提出采用新材料代替钢筋的必要性,介绍了连续玄武岩纤维筋的物理化学性能。建立有限元模型,计算配置两种材料道面的荷载应力与翘曲应力并进行比较。分别计算得到玄武岩纤维筋以及钢筋的3大控制指标,并将结果进行比较,得到应用玄武岩纤维筋代替钢筋具有很高的可行性。By continuous reinforced pavement analysis, the necessity of the use of new materials to replace the reinforcement bar is brought forward.The physical and chemical properties of the continuous basalt fibre reinforcement are introduced.By setting up finite element model,the load stress and the warping stress of the two materials pavement are calculated and compared.The three major control indicators of basalt fibre reinforcement and reinforcement bar are calculated,then the results are compared.The results show that replacing reinforcement bars by basalt fibre reinforcement has a high feasibility.
