公路预应力混凝土圆管涵结构计算方法的建议

A PROPOSAL FOR THE STRUCTURE CALCULATION METHOD OF HIGHWAY PRESTRESSED CONCRETE CYCLOIDAL CULVERTS

本文依据现行桥涵设计规范,对预应力混凝土圆管涵设计问题进行了讨论。从内力组合、应力计算和环向预应力损失等方面,建议了环向结构的计算方法。文末给出了计算示例,供设计参考。

In this paper, the design problem for prestressed concrete cycloidal culvertsis disscussed on the basis of the current design code for highway bridges andculverts. The method for calculating circumferential structure is proposed onthe combination of internal forces, stress calculation, circumferential prestresslosses, and so on. Finally, a practical example is given for reference whendesigning.
