摘　　要：本文提出了用N次抛物线推求空腹拱式渡槽主拱圈拱轴线以及考虑不同荷载组合时对拱轴线进行调整的方法。该法可根据不同上部结构布置情况构造出一条与压力线相当逼近的最优拱轴线,使主拱圈具有良好的受力状态。In this paper a method of calculating the axis of main arch ring for open spandrel arch aqueduct by uing the n-th power parabola and comprehensively adjusting the axis on the basis of different combination of loads is proposed. Using this method, an optimal arch axis quite approximating the pressure curve can be fairly formed according to different arrangement of superstructure, the main arch ring will be provided with favourable mechanical properties.
