用有效活载挠度确定钢筋混凝土桥面铺装层的厚度

Using the Equivalent Design Deflection to Determine the Thickness of Bridge Deck Pavement

本文将桥梁铺装层及桥梁结构简化为弹性层状体系的力学模型 ,利用有效活载挠度作为设计弯沉值 ,计算了桥面柔性铺装层的厚度范围 ,供生产实践及相应规范指定参考。

This bridge deck pavement composed of asphalt mixtures and bridge structure is simplified as a model of elastic layered system. Permissible deflection of bridge span is converted as equivalent design deflection of the layered system. Based on the above, the required thickness of deck pavement is calculated by means of elastic theory.
