桥面铺装设计理论的研究

A Study on Design Theory of Cement Concrete Bridge Deck Pavement

通过结构的线弹性理论 ,考虑桥面铺装层本身的功能要求 ,对混凝土桥水泥混凝土桥面铺装层的受力进行了简化 ,并根据实际状况提出了若干假定 .在此基础上 ,提出了以梁板体的最大弯矩为基础 ,以桥面铺装开裂和剥离为控制指标的水泥混凝土桥面铺装的计算方法 。

By applying the theory of structure elasticity,this paper first gives an account of the function of the cement concrete bridge deck pavement, then simplifies the forces on the pavement and finally makes some hypothesis according to the realistic conditions. A design method is presented on the basis of the maximum moment of the force on the whole bridge and with the crack and fracture of cement concrete bridge deck pavement as the controlling index. An example and range of suitable use are also given in the paper.
