行车荷载作用下水泥混凝土路面力学性能分析

摘要

采用有限元方法,建立计算模型,对行车荷载作用下水泥混凝土路面的力学性能进行了研究,重点分析了面层、基层和土基强度、面层厚度及车辆荷载等不同参数对路面力学性能的影响.%Since the widespread use of cement concrete pavement at the beginning of the 20th century,the load stress of cement concrete pavement has been an important research topic that people pay great attention to.With the development of computer technology applications,various finite element methods are applied to the stress analysis of cement concrete pavement.In this paper,the finite element method is used and the finite element calculation model is established to calculate the influence of different parameters such as surface layer,base layer and soil strength,surface layer thickness and vehicle load on the mechanical properties of pavement.
