| 摘 要： | 以Marc有限元软件为工具,对道面面层和接缝用板单元进行模拟,考虑面层和基层之间的界面接触,建立了基于＂地基—道面结构—飞机轮载＂的相互作用的足尺9块板水泥混凝土道面三维有限元模型,应用该模型,计算了飞机当量单轮荷载作用下刚性道面结构的力学响应,得出道面各结构层模量对板底应力的关系。

| Abstract: | By finite element software Marc,pavement surface and joint plate element were simulated,and the three-dimensional finite element model of cement concrete pavement of 9 full-scale slabs on the basis of interaction among of ground,pavement structure and dynamic plane load was established thinking on interfacial contact between surface and base.Rigid pavement structure mechanics response of equivalent single-wheeled load action was calculated,and relationship between layer modulus of pavement and bottom slab stress was made. |

| Keywords: | joint plate element interfacial contact structural response three-dimensional finite element |
