摘要
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,介绍了小板块水泥混凝土路面温度应力的计算原理,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温度应力进行分析,探讨了小板块水泥混凝土路面结构层参数对其温度应力的影响规律,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了有益的参考.
This study aims to address the main disease of cement concrete pavement structures of rural highways in recent years.We give an introduction to the calculation principles of temperature stress for small slab cement concrete pavement.On the basis of the software of finite element method(ANASYS) and by adopting 3-D FEM,we analyze the temperature stress for small slab cement concrete pavement.We also discuss the influence rule of pavement design parameters for temperature stress,and thus provides a useful reference for the design,application and future research on small slab cement concrete pavement structures of rural highways.
