摘　　要：AASHTO水泥混凝土路面设计方法在国际工程中应用广泛。研究以玻利维亚尤圣道路项目为例,按照AASHTO规范方法进行水泥混凝土路面结构设计。基于PCA疲劳修正模型,利用ISLAB2005有限元软件分析水泥混凝土路面结构受力性能。结果表明:在行车荷载作用下,最大拉应力一般出现在面板顶部位置。当面板厚度为20cm时,结构满足抗裂要求。In international engineering,AASHTO cement concrete pavement design method is widely used.In this paper,taking the Yucumo-San Borja highway project in Bolivia as an example,the structure of cement concrete pavement is designed according to the AASHTO specification method.Based on PCA fatigue modified model,ISLAB2005 finite element software was used to analyze the stress performance of the structure of cement concrete pavement.The results show that the maximum tensile stress generally occurs at the top of the pavement surface under traffic loads.When the thickness of the pavement surface is 20 cm,the structure meets the crack resistance requirements.
