Abstract: Aiming at a series of mechanics problem on overlaying asphalt on the old cement concrete pavement，mechanics model and numerical analysis method were adopted to explode and research. Fortrango language was applied to computing the procedure for dimension，and an example analysis Was given．All the results of the computing were consistent with the Ansys software imitating results and the local test results．The model is proved to be reasonable in theory and has important and actual meaning for future investigation on asphalt overlay．

Key words: concrete pavement, asphalt overlay, mechanics model, numerical analysis

摘要： 针对目前旧水泥砼路面加铺沥青罩面层的一系列力学问题，从力学模型的角度，采用数值分析方法进行了探 索和研究．包括二维简化模型分析、三维模型分析等几个主要部分最后针对二维、三维算法分别应用Fortran90语言 进行计算机程序设计，作了算例分析．所有数值计算结果和Ansys软件仿真结果及现场测试结果基本吻合，从而说明 模型研究方法在理论上是合理的，对于进一步探索旧砼路面修补技术具有重要实际意义．
