公路水泥砼板厚及混和料配合比设计

The Thickness of Highway Cement Concrete Plate and Proportioning Design of Mixture

据文献［１］和［２］，对公路水泥砼板厚及混和料配合比（经验公式法）进行了程序设计，并用例子分析了砼疲劳寿命Ｎｅ的影响因素的显著性，得出：面板厚度、砼弯拉强度、纵缝拉杆设置的质量（考虑了Ｋｒ的取值及运营后的失效性）对Ｎｅ的显著性很大，而依据文献［１］，则Ｅｔ对Ｎｅ的影响较小，Ｅｃ的设计取值范围较小，其对Ｎｅ的影响也较小。

According to reference material (1) and (2),the paper introduces the program design of the thickness of highway cement concrete plate and mixture proportioning.And with examples,analyses the remarkableness of concrete fatigue lifetime N e factor.
