针对曲面底扩散陡槽内急流特点采用沿水深的积分方法,并考虑曲率、底坡及底摩擦对流动的影响,将三维水流运动方程组简化为二维水深平均流方程,并导出了水深平均流的特征方程组;结合抛物柱面底扩散陡槽工程实例采用特征差分法进行数值计算,通过逐时段内插,调整计算点分布可克服特征线方法计算点分布不规则的缺点,使计算结果便于实用.

Depth—mean-flow equations have been derived．through 2-D mean simplification of integration for 3·D folw equations along depth，for super—critical flow in divergent chute with curved bed，in which the influenceof curvature，bed slope and bottom friction on flow are considered．Based on depth—mean—flow equations，characteristic equation system are presented．Numerical characteristic FDM solution has been given for a diver—gent chute with parabolic prismatic bed surface in engineering．Problems for irregular distribution of characteristic mesh points have been solved by interpolating adjustment of computation points for every time step，SO thatthe results can be used conveniently in practical application．
