| 摘 要： | 回弹弯沉值能反映路基路面的承载能力，通常用于路面结构及旧路补强的设计。但规范中弯沉值的计算值往往偏大，结合一实例对其进行验证，并推荐一种弯沉值的确定方法，能更真实地反映路基路面的承栽能力。

| Abstract: | The rebound deflection is used to represent the subgrade bearing capacity,which is not only used in the pavement structure design,but in the old road reinforcement design.However,the deflection calculated according to the code is usually big.Incorporating with one example such conclusion is demonstrated,in addition,another one calculation method of deflection is recommended,so that the subgrade bearing capacity could be reflected more truly. |
