Finite Element Analysis of Vehicles-load Stress for Small Slab Cement Concrete Pavement

针对近年来农村公路水泥混凝土路面结构中出现的主要病害问题,介绍小板块水泥混凝土路面荷载应力的计算原理,以通用有限元软件ANSYS为基础,采用三维有限元法,对小板块水泥混凝土路面的荷载应力进行分析,探讨小板块水泥混凝土路面结构层参数对其荷载应力的影响规律,为目前农村公路小板块水泥混凝土路面结构的设计应用及其后续理论研究提供有益的参考.

Aiming at the problem of main disease of cement concrete pavement structures of rural highways in recent years, the calculation principles of vehicles - load for small slab cement concrete pavement has been introduced, on the basis of the software of finite element method （ ANASYS ） , 3 - D FEM is used to analyze vehicles - load stress for small slab cement concrete pavement. It discusses the influence rule of pavement design parameters for vehicles - load stress, and provids the beneficial reference for current design, application and the following fundamental research on small slab cement concrete pavement structures of rural highways.
