弹性层状体系弯拉应力近似计算

Regression Formulas of Tensile Stress in the Elastic Multilater

摘要: 在笔者已有工作的基础上，对常见路面结构的弯拉应力作了大量的计算和分析，修改了柔性路面中层弯拉应力回归逼近的数学模型。提出了两个中层弯拉应力的近似计算公式。精度分析表明这两个近似公式的精度可以满足工程设计和理论研究的需要

Abstract: The regression formulas are presented based on the analysis of elastic multilayer theory and author’sprevious researches. The regression mathematical model of tensile stress in the middle layer of the three-layerpavement is modified.A number of results of regression foimulas shows good accuracy for engineering application.
