摘要
在一般情况下，曲梁的预应力等代荷载公式比较复杂［２］，不便于应用。如果预应力钢筋置于某个圆柱面内，则不但公式大为简化，而且可用圆柱展开面上钢筋曲线的几何特性表达等代荷载。公式不仅几何意义明确，而且将空间计算化为平面计算，因此更具实用性。
In general cases, the formula for calculating the equivalent load of prestressing force in curved girder is rather complicated and inconvenient to use. If the prestressed reinforcement is arranged in certain cylindrical surface, the formula can be simplified peatly and the equivalent load can be expressed by the geometric property of curve of the reinforement along the developed cylindrical surface. This formula not only has clear geometric meaning, but also can change the space calculation into plane calculation. So this formula has peater practicality.
