摘要: 为方便沥青路面结构设计生产、教学、科研之用,本文采用分析综合法与分离变量法建立了弹性三层体系应力位移显式模型;并在分析常见路面结构层厚度及其当量换算和模量变化范围的基础上,成功求得了三层体系路表弯沉、上层滑动应力、上层连续应力、中层应力逼近公式;精度分析表明本文逼近公式精度很好,完全可推广应用于多层体系,满足工程设计和有关理论研究的需要.

关键词: 沥青路面, 弯沉, 弯拉应力, 逼近公式

Abstract: To facilitate the design, teaching and research of asphalt pavements, the article founded the models of displacement and tensile stress of three-layer system by using separation of variables, analysis and synthesizer.Based on the analysis of common pavement structures and their equivalent conversion, the regression formulas of displacement and tensile stress are obtained successfully, furthermore the formulas applied in multi-layer system are checked.A great number of results of regression formulas show good accuracy for engineering application and theory research.

Key words: asphalt pavements, displacement, thensile stress, regression formulas
