浅谈预应力混凝土异型空心板桥配束计算

预应力空心板桥是中小桥常用的一种形式，由于其结构跨径较小，结构形式简单，其设计理论与施工方法都比较成熟。本文对其进行理论计算及截面积几何性质计算，极限承载力计算，预应力承载力计算，预应力损失计算，施工阶段正常使用阶段应力计算，挠度计算，对其截面配筋并进行了强度计算。然后用“桥梁博士”进行结构分析，较好的把理论与实际相结合，完成其配束设计。

Priestesses Concrete Hollow Slab With Profiled Beam Calculation

Priestesses hollow slab is a form of small bridge is commonly used, because its structure is smaller span, simple structure, its design theory and construction method are more mature. In this paper, theoretical calculation and cross -section geometry properties on the calculation, calculation of ultimate bearing capacity, the calculation of bearing capacity of priestesses concrete, priestess loss calculation, calculation of the deflection, stress calculation of construction stage during normal use, the reinforcement and the strength calculation. Then use the ＂bridge＂ to analyze the structure, good to the combination of theory and practice, to complete the design of tendons.
